Sinn U1 on Strap

Product Details

The technology and design elements used to create the Sinn U1 go far beyond standards used at most watch companies.

The U1 case is made from the same steel that is also used in the construction of the outer hull of submarines. The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany�s North Sea shipbuilding yards who construct submarines from the very same steel.� This special steel is also amagnetic which means that is does not have magnetic properties and cannot itself become magnetized.� The watch movement itself is protected from magnetic fields up to 4,800 A/m.

Because of the special steel used from the submarine steel manufacturer, the case resists the effects of exposure to salt water and salt water environments.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel and is Tegimented. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. The international testing lab of Germanischen Lloyd has tested the U1, and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

Matte black dial with date at 3, Super Luminova on hands and markers, and striking red seconds hand complete the design. Other features include sapphire crystal with anti-reflective coating, and silicone rubber strap with double push deployant buckle and fliplock safety clasp.

"Sinn U1"

Posted by: John Wagner

Comments about this watch: I've been collecting watches for many years, especially divers and I have to say the Sinn U1 ranks up there with the best. Love the sub steel look and durability, the dial is unique from a distance and extremely legible. Movement is very accurate over the past several weeks gaining about 1 sec per day. Rubber strap is very comfortable and the 44mm case is comfortable due to the off set crown. All around great diver watch!

"Watch Saved My Life!"

Posted by: Oliver G.

Comments about this watch: I bought the Sinn U1 while in Singapore for a ship repair. I had never heard of the Sinn brand, but I was impressed with the build quality and the uniqueness of the watch. The thick rubber band saved me this last summer while shucking oysters! The knife slipped and went straight through the band, stopping at my wrist! I highly recommend the Sinn line to anyone. I also have a vintage Rolex Submariner Date and a new Rolex Explorer II, but I find the Sinn U1 to be the most unique and interesting of... - more details

"Awesome watch!"

Posted by: Floyd H.

Comments about this watch: There are a number of reasons I love this watch. 1. Build and quality is superb. I wanted a watch that can take any abuse in daily wear yet remaining comfortable on my wrist. The rubber band is super comfortable. In fact I wore it to sleep on a first day without noticing it's there. 2. Accurate and Reliable automatic movement. While wearing it I don't feel the "winding" experience like any other automatic movement. 3. Perfect size. I have a small wrist 6.5" yet 44mm (lug to lug) x 15mm (height) ... - more details

"Awesome!"

Comments about this watch: I just received the U1 today. All of the pics I've seen don't do the watch justice. I'm totally amazed, Tim, Rob and Matt are top notch. The transaction was as smooth as silk and delivery was right on time. WatchBuys and staff are a class act and will be hearing from me again.

"Amazing!!!"

Comments about this watch: I purchased my first U1 last year and stupidly flipped it. Purchased my second U1 yesterday and it is all I remember it was. A very solid, well made very comfortable German watch. With arguably the most unique watch face out there.

"Two years on my wrist"

Posted by: Rene Decquir

Comments about this watch: For once I bought an automatic watch that is easy to to set and is very accurate and indestructable. It is quite scratch resistant and the ruber band is still holding up.

"Shockingly awesome watch"

Posted by: Frank Gregory

Comments about this watch: Great solid watch with more technology than any other diver watch besides the Sinn U2. Although not a chronometer it runs like one. Very pleased.

"Workmanship"

Posted by: Jason R.

Comments about this watch: Just got my U1 today and I was blown away by how well thought and well made this watch is, I came in with high expectations but having never seen a U1 (or Sinn for that matter) in person it handily beat my expectations. great watch, great company. (other watches Rolex Subdate & Panerai 111)

"Great Watch."

Comments about this watch: This watch looks awesome. Wears great. I've not taken it diving or put it though any hard core abuse,but it does keep GREAT time and just feels great to wear. I have 6 other watches and this one has not left my wrist in a while.

"LOVE IT!"

Posted by: Cliff Geocos

Comments about this watch:

The U1 is a great looking watch that wears like a 40mm.

It`s very comfortable, even on my fairly small wrist. I`ve had it for 3 days now and it`s only 3 seconds fast! It's a great buy, and getting it from WatchBuys you can`t go wrong, they`re great too! Thank`s Matt!

"Absolutely recommend"

Posted by: Ryan A. Haqq

Comments about this watch: I'm a recent college graduate, and bought the U1 to be my everyday watch. I have worn it almost entirely for the 7 months I've had it (taken off for showers and exercise) and am just as thrilled with it as the day I received it. It's accurate, robust, legible, and unique.
