Perfect watch for all occasions

"Perfect watch for all occasions"

Verified Owner Comments: I ordered this watch on a Friday evening and received an email / phone call Monday to confirm my delivery address. The customer service delivered is outstanding & should serve as an exemplary model.

I received the watch Wednesday ( a day earlier than promised delivery date ) so I was happy about that as well. The watch wears perfectly on my 6.25 wrist. It was my first time adjusting a steel bracelet and it was not difficult at all using the provided tools in the packaging.

Overall, I am happy with this watch I have been wearing it for three weeks straight and have no complaints whatsoever.

Fantastic watch and buying experience

"Fantastic watch and buying experience"

Verified Owner Comments: I was stuck buying an Omega Aqua Terra or a Rolex Explorer and really couldn’t justify paying for either one. I found Sinn and the 556i and I have to say I absolutely LOVE this watch. Beautiful, rugged, masculine, refined, and a perfect size for my 7” wrist, plus it’s just a bit more unique than the Rolex or Omega. I have no desire whatsoever for a either of what were my grail watches now.

The Sinn 556i is "My” watch. As for watchbuys, I had a fantastic experience. Called before placing my order online to ask a few questions. The man I spoke with was very helpful and courteous. Ordered online later that day and had my watch a few days later. If I decide to buy another watch (Sinn 104... hmmmm) I’ll be more than happy to buy through watchbuys.

Wonderful watch!

"Wonderful watch!"

Verified Owner Comments: This was a big purchase for me to commemorate something special. I wanted a keeper that would last and fit most (if not all) circumstances, and I did a lot of research first before settling on the 556i. Matt at Watchbuys was really helpful with my inquiries prior to buying, and the service was great throughout.

The watch itself is amazing, I am very happy with it. I have smaller wrists at around 6.25 inches, and the watch fits perfectly. The bracelet is also very comfortable, and easy to adjust. It looks amazing. The black/white contrast on the dial is stunning, and looks great in all light conditions. One thing I was really impressed by was how white the hands and indices stay even though they are lumed - no green tinge at all unless you're in the dark, which is amazing.

I've found the lume itself to be great too, visible all through the night. In short, wonderful watch, very happy with the product and the service from Watchbuys!

Fantastic Value

"Fantastic Value"

Verified Owner Comments: This is a compactly sized sport watch that can be dressed up. Sapphire crystal with AR coating in both sides, solid end link bracelet, and drilled lugs allow for great versatility, durability and visibility. If you only buy one watch in your life, this should be on the list.

Watchbuys service has been fantastic. Quick delivery, and phone call confirmation and friendly support. Will be shopping here in the future again. Do yourself a favor and buy this watch, you will not regret it.

First Watchbuys Purchase

"First Watchbuys Purchase"

Verified Owner Comments: After some thought I decided to buy the Sinn 556i. Minutes after my online purchase, Watchbuys called me up for confirmation and just two days later my watch was in the mailbox in perfect condition.

I will absolutely look at Watchbuys for future purchases.

Future classic.

"Future classic."

Verified Owner Comments: This is an almost perfect watch for many occasions. It fits many wrist sizes at 38.5 inches, small enough to fit under a shirt sleeve, while still being masculine. 200m water resistant allows me to be unconcerned about getting it wet. The inky black dial gives the watch a premium feel that I feel a matte dial lacks.

The white indices are a perfect contrast. I love the little quality details too. The crown has her wobble and is very smooth, the bracelet uses hex screws in the links, the display case back is sapphire. Many watches costing hundreds or thousands of dollars more don't have these features. Three negatives though. The white indices look awesome during the day but don't glow super well. It would be nice to have a luminous marker on top of the dial to help with orientation at night. I wish it didn't have anti reflective coating on the exterior of the crystal. Minor details that don't overshadow this wonderful piece.

Perfect All Around Timepiece

"Perfect All Around Timepiece"

Verified Owner Comments: After searching for the perfect everyday watch for the better part of a year, I finally decided to order this watch. (I have a 6.5 inch wrist so that eliminates a lot of larger watches) This is the perfect fit, the Lug to Lug is under 46 mm, the 38.5 mm diameter is comfortable yet has great presence on the wrist.

The movement is nicely finished and in the first couple weeks is keeping around +3-4 seconds/day. The bracelet is fantastic and it looks good on every strap I put it on. I cannot recommend this enough, the lume is very adequate, not amazing but still obvious/useful enough.

The WB team was great too, very personalized service, correspondence (whether phone, chat, or email) was always very quick and helpful. Buy with confidence and enjoy this great watch!

Very impressive!

"Very impressive!"

Verified Owner Comments: I put this watch on my Timegrapher as soon as I got it (it arrived running with the time set). It was running with 0 beat error and 0 sec/day gain/loss! This watch is quality all the way. With the glossy and discrete dial, I could use it for work at the office. The only mistake I made was buying the Sinn the same week as my grail watch. My head says wear the grail. My heart says Sinn 24/7.

Perfect Daily Driver

"Perfect Daily Driver"

Verified Owner Comments: This was my first purchase from Watch Buys and it couldn't have been better. Service, knowledge, experience, and quality were all amazing.

I got the Sinn 556I on a bracelet. This is now my daily watch as it is perfect in all regards. Great size, durability, look, and accuracy. Love how I can really dress this watch up/down for any occasion. Great watch, great service. Couldn't be happier.

Perfect GADA watch!

"Perfect GADA watch!"

Verified Owner Comments: Bought this watch a couple weeks ago and it hasn't left my wrist once. Keeping a consistent +3.5 sec/day (BTW, this is my third Sinn watch and they've all run within COSC specs). Can't go wrong with this watch - fits in every situation and looks great while doing it.

Sinn 556 I

"Sinn 556 I"

Verified Owner Comments: A top quality watch. Owned several Sinn watches over time, the 556 I is probably one of the best for daily use. Bracelet is very comfortable.

Fantastic Watch

"Fantastic Watch"

Verified Owner Comments: Ive had this watch now for about two weeks and it hasn't left my wrist im completely satisfied with it. I was a bit hesitant at first about the red second hand or not but im glad i went with the clean white second hand.

Also I don't know maybe i got very lucky but this watch keeps super accurate time. Im talking +5 seconds, and thats since ive gotten it. The bracelet is also fantastic, only problem i had was one of the screws got stuck and broke off when adjusting for size, but Watchbuys made that right immediately after i contacted them about it.

They sent me extra screws and their customer service is great!

Awesome watch!

"Awesome watch!"

Verified Owner Comments: I was on the fence for months before finally ordering this watch. I looked around at so many different kinds, but none of them ticked all the boxes like the 556 does. It meets all my requirements for a true daily watch that can be worn anywhere for any occasion, and looks great!

One main concern I had was the size at 38.5, but now that I have the watch, it's crazy that I was so concerned. My wrist is 7.5 and the watch fits great!

Highly recommend this watch and WatchBuys.....they were great to deal with, sent me constant updates and the watch arrived in perfect condition. Good luck!

Watch Buys and 556i

"Watch Buys and 556i"

Verified Owner Comments: This is my second purchase from Watch Buys and I couldn’t be more pleased. Service is second to none, Knowledgeable, honest, quality products.

My first purchase was a Sinn 856, love that watch, came on bracelet, and when I wanted to put a rubber strap on they were more than helpful, I ordered it and had it next day, just like they said. My latest purchase was a Sinn 556 on bracelet. All other watches are now put away, this 556 is the perfect watch. Size is perfect for my 7 1/4 inch wrist, fit and finish is as good as any of my high end watches. Tha ETA movement in this watch is fantastic, + 2 seconds a day.

All in all a great watch, and a great experience with Watch Buys. I WOULD HIGHLY RECOMMEND not only this watch but also Watch Buys.

First high quality watch

"First high quality watch"

Verified Owner Comments: I did a lot of research prior to purchasing this watch (tons of youtube videos, reviews, etc) finally pulled the trigger and made the purchase. It was a very good decision. Its a very classy watch with very high quality manufacturing - no corners cut. Its now a daily wearer for me and I get a lot of compliments.

Didn't love the bracelet, but service is fantastic!

"Didn't love the bracelet, but service is fantastic!"

Verified Owner Comments: The watch case itself is beautiful, but I wasn't in love with the bracelet - it was a little too loosely connected to the case for my liking. Ended up having a great conversation with Matt about the 556 and eventually decided to return it.

That said, I would buy another watch from these guys in a heartbeat. They stand behind the products they sell and they provide great customer service.

Great service !

"Great service !"

Verified Owner Comments: I ordered two SINN 556I recently. It was my first order with WatchBuys....the watches arrived promptly as discussed with them. From their website to phone (Jon mostly ) to delivery and watch box presentation - I’m very happy with WB and will order again.

Wait! I just did! I preordered the Jaeger & Benziger Anthracite Chrono ...Hopefully, I’m as happy as I was with the SINNs... JD

Good Experience, Great Watch

"Good Experience, Great Watch"

Verified Owner Comments: My first time purchasing through WatchBuys, and my first Sinn. I would certainly recommend them as an online retailer, and if I am looking for another Sinn, Junghans or other German brand this will be the first place I come to.

As for the 556i - I love it. I've been intigued but cautious with this brand as I had never seen one in the metal, and my only regret now that I have one is that I did not purchase sooner. The simplicity of the dial is understated perfection, finishing is top notch and the bracelet was very easy to resize at home.



Verified Owner Comments: Glad I got this on the bracelet. Makes for an any occasion watch

Outstanding medium sized watch

"Outstanding medium sized watch"

Verified Owner Comments: After spending way too much time on YouTube reviews and seeing what's available in a 38-40mm watch with a high quality steel bracelet, the 556 I is an amazing watch value. If you're tired of watches the size of dinner plates buy one of these.



Verified Owner Comments: I had been looking at the 556i for a long while and finally got it for my birthday. It is a fantastic watch and exceeded my expectations. So glad I finally took the plunge.

Couldn't be happier!

"Couldn't be happier!"

Verified Owner Comments:

I bought this watch as a graduation gift for my son, and I am really thrilled with it. The dial is deep black and crisp white, and the layout is graphically very powerful. Although 38.5mm, it lays flat and wears smaller, which is helpful as he (and I) have smaller wrists.

The quality of the machining is astonishing, especially given the price point. The bracelet has a velvety finish and the case is solid and sharp...with a sapphire back! I own other nice watches (Rolex, PP) and this watch holds it's own in comparison.

Watchbuys personnel were patient and complaints whatsoever.

Purchased a Sinn 556i

"Purchased a Sinn 556i"

Verified Owner Comments: This purchase represents my first (hopefully not my last) purchase from I could not be happier with the entire shopping experience, as well as the watch! was very prompt and professional throughout the ordering and fulfillment process. As for the timepiece, the Sinn 556i is, in my opinion, an incredible value-for-money watch. The build quality of Sinn is on par with many watches that are far more expensive. I have and will continue to recommend both and Sinn Timepieces to anyone looking for a high-quality watch.

Best bang for the buck

"Best bang for the buck"

Verified Owner Comments: Bought a Sinn 104 from WatchBuys before, customer service was top notch!

This time the experience was great as before! The 556 with bracelet is a great everyday watch. The build quality is great and I am a big fan of Sinn pilot watches' legibility. People on the forums often compain the 556's lume but I found mine to be great, it keeps legible all night! BTW if you don't know, the 556 has top grade ETA 2824-2 movement, I found it to be better then the Sellita in the 104

Sinn 556 I Bracelet

"Sinn 556 I Bracelet"

Verified Owner Comments: Out of the box, most impressed with the build quality of the watch and the buttery soft bracelet - the most comfortable I’ve worn - including Rolex and many other brands. I was impressed with the clean, minimal design in pictures and even more so on the wrist.

Overall size very comfortable on my 7.5” wrist. First week the watch kept excellent time at 1 and 2 seconds per day. Second week almost over and so far gaining in time to 3+ secs per day. I’ll give the watch the recommended 8 weeks to settle in. Although Watchbuys describes the movement as "Top grade” I do not see that claim on Sinn website.



Verified Owner Comments: Amazing watch! It’s hard to beat the quality and value for your money with the 556. It hasn’t been off my wrist since it arrived several weeks ago.

I also can’t say enough about my experience with watchbuys. They are an outstanding business and Rob, one of the owners, patiently answered all my questions over the phone. I would not hesitate to buy another Sinn or another watch from watchbuys.

Still going strong and looking great 5 years later

"Still going strong and looking great 5 years later"

Verified Owner Comments: I know the 556 is Sinn's entry level but I still love it's simple markings and striking glossy black face even over some of their higher end models.

I'm 6'1 but have fairly thin writs so it's 38.5mm and 12mm dimensions work well for me. While only visible when it's off the window to the movement is a very nice touch. Lume isn't super long-lasting, but I think any more would have given a greenish hue to the markings by day and ruined the beautiful white on black contrast.

Awesome Watch - 5 years later

"Awesome Watch - 5 years later"

Verified Owner Comments: I bought this from WatchBuys in 2013 and have worn it almost daily since. It's a great, beautiful, timeless piece that can pair with almost anything.

This was my first 'real' ($1k+) watch and I bought it after A TON of research. I am very pleased with my purchase, even 5 years later - so much so that I came back to review it. And it's unique - I've only run into one other person with a Sinn since I bought it.

Great Watch

"Great Watch"

Verified Owner Comments: This Sinn is great! Very well executed case and gloss dial, which makes it highly legible. It's a bit on the small side, but it is great for smaller wrists and for a change from larger dive watches. Very versatile on bracelet, natos, leather, and almost any other strap.



Verified Owner Comments: Such a timeless design and so versatile. Put it on NATO straps and dress it down or leather strap/bracelet to dress it up. You really can't go wrong with this one.



Verified Owner Comments: The quality of the case, bracelet, and movement Is amazing! Shipped fast and arrived well packaged as well.

Also, the folks at WatchBuys are top notch in customer service and they are truly passionate about watches. I highly recommend!

Why did I wait so long?

"Why did I wait so long?"

Verified Owner Comments: I do not know why I waited so long after trying the Sinn 556i at several WatchBuys shows. It is perfect for me. It sits very comfortably on my 7 wrist and is easily legible day or (most of the) night. In the first 10 days it has gained a total of 13 seconds I assume it get better as it wears in! The watch looks great on the four after market straps I've tried in addition to the very comfortable and attractive bracelet.

Attractive, legible, comfortable, tough and works in the yard or office - there's not much more to say.

Very happy!

"Very happy!"

Verified Owner Comments: I am very happy with my overall experience with WatchBuys. Matt was great and answered all of my questions thoroughly. The watch arrived exactly when they said it would and I received a follow up call shortly after placing my order just to make sure all of my questions were addressed.

As for the watch itself, I couldn’t be happier. The Sinn 556I is a well built watch that offers tremendous value for the price. I own several watches at higher price points but this one takes the crown for the best bang for the buck. The fit and finish of the Sinn 556I rivals that of watches costing several times more. It runs well within COSC parameters, sports 200m of water resistance, is shock-proof and also anti-magnetic.

What I enjoy most about the watch is its versatility. This is no doubt a tool watch given all the features. But at the same time, it can be dressed up with a suit at the office – it looks great for all occasions. The simple, clean, minimalist dial is what makes the watch so appealing. This is the kind of watch that you can wear to the beach and at the same time look equally appropriate in an interview.

I highly recommend the Sinn 556I and WatchBuys!
