Limited editions can be a risky thing—taking an existing and already well-received watch and revising it significantly enough to justify its existence, but also making sure the changes don’t ruin all that was good with the watch in the first place can be quite the challenge, and we’ve all seen our fair share of misses from brands. Sinn, however, seem to have a lot more hits than misses in their back catalog and plenty to choose from in the last few years alone, be they divers, chronographs or three-handers. Although not intended to be a definitive collection, today’s list takes a look at some of our favorite past limited editions from the beloved German brand.
First on our list is the 356 Isetan, a 2016 collaboration with noted Tokyo department store, Isetan. The 356 Isetan features the same 38.5mm case and Sellita SW500 movement (Sinn had already switched from the Valjoux 7750 at this point), but here the running-seconds register and day/date displays are removed to leave a clean and symmetrical dial. The watch retains a domed acrylic, and the hands and indices are painted with “old-radium”-style Luminova for a bit of a vintage vibe. The watch comes on a rich, brown leather strap. Only 50 of these were ever produced.
As Sinn’s iconic Diver, the U1 has had more limited editions replica watches than any other reference, including the recent U1 Professional and Blu1 releases, but it’s the U1-D “Dune” that I’m giving the honors to here. Released in 2015 in collaboration with The Hour Glass, one of Asia’s largest watch retailers, the Dune replaces the iconic red accents of the mainstay model with a more muted sand-toned finish for the hands, bezel markings and dial text. The Tegimented submarine steel case features a hardened black coating along with the bezel, crown and case back. Bringing it all together, the dial is a matte grey with darker charcoal-grey, lumed indices. This one is limited to just 350 units.
A 2015 collaboration with German magazine, Chronos, the Sinn U2c fake watches UK another serious tool diver from the brand. Using the same case as the regular U2 model—44mm of black hard-coated, Tegimented submarine steel—the U2c does away with the GMT hand and accompanying 24-hour scale on the inner portion of the dial and leaves only white and grey markings against a deep black dial and bezel. Inside this stealthy looking beast is the ETA 2892-A2. The watch also features Sinn’s Captive Bezel, Ar-Dehumidifying and Temperature Resistant technologies, and it’s water-resistant to a whopping 2,000 meters. Only 50 were ever made, and the entire run sold out quickly.
