Introducing: The Sinn U1 DS Limited Edition

Introducing: The Sinn U1 DS Limited Edition

Quick Take

With the onset of spring comes an increased pace for new watch announcements — not to mention warmer weather that has us daydreaming about days in the ocean. Right on cue, last week Sinn announced its latest limited-edition diver, the U1 DS. Limited to 500 units based on a full-sized U1 and crafted from hardened submarine steel, the U1 DS sports a special dial created via a grinding process that gives each example a unique finish.

Initial Thoughts

Regardless of spec, the Sinn U1 is one of the toughest and most focused dive watches on the market today. One of the German brand’s most well-known designs, the U1 is 44mm wide and 14.7mm thick with a case, bezel, and bracelet made of tegiment-hardened steel (literally the same stuff used for German submarines). Water-resistance is a whopping 1,000 meters. The Sinn U1 DS comes fitted with a flat sapphire crystal, a screw-down crown at four, a unidirectional dive bezel with a luminous pip at 12, and plenty of lume on the characteristically stoic high-contrast dial.

Being a Sinn – and a U-series dive watch – the U1 DS is also low-pressure resistant, waterproof to the specifications of DIN 8310, and designed in accordance to the diving standards of DIN 8306 and tested to Euro diving standards EN 250 / EN 14143. Finally, all of this deep-diving ability is certified by DNV GL, a Norweigan registrar and classification society that validates such compliance.

With a date display at three, the Sinn U1 DS uses a Swiss-made Sellita SW200-1, which ticks at 4 Hz and offers a power reserve of around 38 hours. Given the price point and the intent of a watch like the Sinn U1, the Sellita is a solid choice that should operate reliably and require relatively minimal maintenance across the life of the watch.

Really though, the U1 DS is just a limited and eye-catching take on the otherwise very calm and collected U1. Limited to 500 pieces at $ 2,750 for the rubber and $ 2,850 on the steel bracelet, with its interesting and uncommon dial finish, the Sinn U1 DS adds a bit of collectible fun and flair to the brand’s rough-n-tumble tool diver.
