Product Details 

In creating the Sinn 556 I, Sinn's goal was to offer their most affordable watch in the line, while at the same time maintaining the quality and engineering standards that have set Sinn apart.

The Sinn 556 I features a case size at 38.5 mm which is satinized. This finish results in a slightly more polished look without the shiny "mirror look". In addition, the dial used for the Sinn 556 I features indices ("I") rather than Arabic numerals for a very clean layout.

Other features of the Sinn 556 I include:
  • Case in 316L surgical stainless steel which is satinized
  • Sapphire crystals on both sides of the watch
  • Double coated anti-reflective covering
  • Dual seal crown lock to improve water resistance
We love the Sinn 556 I, and feel that it offers outstanding precision and engineering at an attractive price.

This watch is fitted with a Sinn black calf leather strap with black stitching and tang buckle. Water resistant to 200 meters.

"Sinn 556 I"

Posted by: Sean C

Comments about this watch: Fantastic build quality, I'm very satisfied with this watch. Simple design will look current for many years. Strap seems to be well built and has a nice leather smell. I have small wrists and it doesn't look too big. Recommended.

Comments about this watch: I am extremely pleased with my purchase of a Sinn 556 I. The watch is even better looking than in the pictures and reviews that caused me to buy it. WatchBuys customer service personnel are extremely knowledgeable and helpful no high pressure sales pitch. All my questions prior to and after the sale were thoroughly answered and the watch was sent out for prompt delivery. This will not be my last purchase from this company.

"Quality, versatility, elegance all in one package"

Comments about this watch: This is a watch that fits in really well in a business casual setting, weekend BBQ party, or formal / suit & tie environment. No tegimented case or other technology is included, however. But I LOVE its simple, understated design that screams quality all around. This is my first Sinn purchase, and likely it won't be my last.

"Sinn Excellence"

Posted by: Sumeet S

Comments about this watch: This watch has a super clean design and a flawless finish. I like the satinized case a lot as well as the focus on telling the time without any distractions. Turning the watch over gives you a look into the 25 jewel movement through a sapphire back. All in all this is a tremendously satisfying watch to own.

"Great watch and great customer service"

Posted by: Dawson

Comments about this watch: Would I like a tegimented watch? Sure, but aesthetically this is in my opinion the best looking watch out there. I love the look and feel. Customer service was top notch too, it was on back order for a week but they received a shipment from Sinn early and promptly gave me a phone call to let me know it was on its way, explain the return policy, and ask if I had any questions. I'll definitely order from them again.

Comments about this watch: Great watch, reminds me of the clocks at a German Airport. Little on the small side at 38.5 mm, but outstanding build quality makes up for it.

Comments about this watch: It would have saved me a ton of money over the years. I am completely satisfied with the watch and WatchBuys support. Perfekt!!!

"Excellent Service"

Posted by: Mark

Comments about this watch: Purchased the Sinn 556 I in Canada. WatchBuys staff were excellent. I have received many comments on my Sinn 556 I. It is very comfortable (easily wearable with a dress shirt cuff) and is a classic design that looks good in a professional workplace, or just out on a boat. Also it easily readable at night. Highly recomended!

Comments about this watch: I bought a 556I from WatchBuys in January. Here are my initial impressions. WatchBuys was great, professional, pleasant to talk with, performed all tasks as scheduled, and very communicative. Packaging, first-rate. The watch itself is exactly as hoped - classic, elegant, and well-designed and made.

Comments about this watch: This watch is beautiful with the super black face and bright white contrast of the hands and markings. Highly recommended.

"Follow up"

Posted by: Thomas Hume

Comments about this watch: Follow up on a 556 I got not too long ago. Still love it. Am going to start selling all my other watches, no need for them any more. Picked up a Sinn rubber strap with deployment. The 556 looks great with it. It's all the watch I need.

"First but not last...."

Posted by: Doug C

Comments about this watch: I have been intrigued by Sinn's for a few years now, and finally decided to purchase a 556. Wow! What a bargain. This watch just reeks quality, far beyond other brands at this price point. One of the top levels of ETA's tiers for their calibres, I wes impressed that it even included blued screws. This is unheard of at this level. I have two complaints, and believe me I have tried to find faults. 1) I would prefer a matte finish to the dial. This version is slightly shiny (yes, I know this is sub... - more details

Comments about this watch: A beauty. My eyes are not the best and I have no problem reading the numbers. Classic design. Ausgezeichnete Uhr.

"Beautiful Watch!"

Posted by: Tony

Comments about this watch: I couldn't be happier with the purchase. I wanted the metal bracelet but it was sold out. I have to say it looks great on the black leather strap as well. It shows off the case nicely and gives it the appearance of greater thickness. It fits my 6.75" wrist perfectly. It also looks great on a brown strap. As soon as the metal bracelet becomes available, I'm all over it! Great value!!!

"Beautiful and understated"

Posted by: Smedley

Comments about this watch: This is a beautifully made and elegant watch. I'm a pretty big guy, but the relatively small diameter still looks appropriately sized. I'm very impressed by how good the piece looks, yet it's not in any way ostentatious or fussy. The transparent back is fascinating as well. Highly recommended.

"Amazing watch"

Posted by: Jon

Comments about this watch: Very happy with the quality of this watch. Sinn has gone back to using top grade ETA 2824-2 movements in the 556, and mine keeps excellent time for an automatic. The level of finishing on the movement is excellent. Don't like the strap that came with it and couldn't justify the cost of a bracelet, but the strap is easy to change and you can always buy a bracelet from WatchBuys later. I have a green zulu and a brown di modell jumbo that both look very sporty with the 556.

"Nice watch!"

Posted by: Dave

Comments about this watch: I just got a 556 after the holidays, and I can't stop wearing it! I have TAGs and an Oris, too, but this watch is different from Swiss watches and has so much character. It has a really solid, Teutonic feel to it. The dial is extremely easy to read and the nighttime lume is also quite good. So far over the past couple weeks, it is keeping bang-on time as well. The 556 is a solid watch and a great value. It has a definite feel of no-nonsense quality, durability, and masculinity, and a classic des... - more details

"Classic style, great wearing watch"

Posted by: Ed

Comments about this watch: It wears bigger than its 38.5mm. I have a 7.25'' wrist and it's a perfect size.

Comments about this watch: I've had my 556 for a few months now. Works like a champ and looks great with any wardrobe, from the gym to business meetings. Negative: Scratches on bezel are highlighted by finish. Still not a deal breaker.

"Sinn 556"

Posted by: James Reedy

Comments about this watch: Gorgeous watch at a fantastic price. However beware the satinized finish isn't very durable. The 316L steel is quite soft and the grain in the satinized finsh will show even the slightest scratches, ESP those that run perpendicular to the grain. Also the hard edges around the bezel and case ding easily owing to their sharpness. Still it's a great watch at a reasonable price, no regrets.

"Sinn 556 on Strap - Superb Value & Build"

Posted by: Mark

Comments about this watch: I just received my first Sinn watch yesterday. The value of this watch is incredible. From the moment I took it out of the box I could tell that the build quality was that of watches that are much more expensive. This watch feels so solid on my wrist yet it is not oversized. I do have a smaller wrist and this 38mm watch fits it perfectly. I would highly recommend this watch to anyone wanting a solid design, German craftsmanship/engineering, great value, small or medium sized wrist, someone maybe... - more details

Posted by: Santo

Comments about this watch: I have a collection of almost 40 watches and this is likely to become my everyday wear watch. This watch feels good on my wrist unlike some others that pinch or have sharp edges. The crown is set in such a way that it doesn't dig into my wrist when I flex my wrist. The black and white dial and hands present very well thus making this is an easy to read watch without my glasses. I am already receiving complements on my latest addition. The price point can't be beat for this timepiece. The crystal... - more details
