Product Details 

Step up to the EZM 5 Professional Series with the Sinn U2. The technology and design elements used to create the Sinn U2 go far beyond standards used at most watch companies.

The Sinn U2 contains all the great features of the Sinn U1, but adds the following:

  • Second time zone complication indicated by a red tipped hour hand
  • Increased water resistance to 2,000 meters
  • Special inert gas mixture
  • Two copper sulfate absorbing capsules
  • 4.6 mm thick sapphire crystal

The Sinn U2 case is made from the same German 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 Germanys 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 which 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 U2, and determined that the watch can be certified as water resistant to 2,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

The Sinn U2 has full UTC functionality through the use of an additional short red tipped hour hand which can be set independently from the primary time zone and indicates the second time zone using a 24 hour display. Screw down crown. The U2 features an inert gas filled cavity with two copper sulphate humidity absorbing capsules, one of which is visible at 6.

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 hardened anti-reflective coating, and silicone rubber strap with double push deployant buckle and fliplock safety clasp.

"Great watch - Great WatchBuys"

Posted by: Mike

Comments about this watch: This is a wonderfully crafted watch and as durable as they come. The quality and design is outstanding.

WatchBuys was great about answering questions at time of purchase. Unfortunately, about 6 months after I received the watch, it stopped working. As I was in Japan at the time, I had an authorized repair shop (this watch is gas-filled so you don't want to take it to just any shop) do the repair. Cost me about $100 to fix, but haven't had any trouble since.

This experience should not deter you from purchasing this watch. It is one of the best in my collection!!

Comments about this watch: The build quality of the U2 is superb; easily on par with Rolex, Omega and Breitling which I've owned.

The watch is big, but does not feel big on the wrist. Face is extremely legible. Very pleased with this watch.

The service I received from WatchBuys was second to none. Matt even answered a general question on a Saturday - even though WatchBuys isn't open!

Watch arrived as ordered, brand new in box and with no surprises. Sinn is a great brand. WatchBuys is a great retailer.

Comments about this watch: Impressive weight! As always the U series is a no brainer especially when it's an EZM watch.

I strongly recommend picking up the leather strap with red stitching as well...simply stunning!
