First up is the Sinn 104, a 3 hand model with a Selitta SW 220-1 26-Jewel Automatic day/date that is reminiscent of many models past and present, yet has a personality all it’s own. The 104 immediately and intentionally calls to mind the 103 Flieger Chronograph, which we recently reviewed, by utilizing the same case, bezel, hands and a generally vintage feel. The dial drops the numerals all together for a very clean and handsome look that is sporty, yet not dress inappropriate.
In a move that largely contrasts Sinn’s own trends from the last few years, the 104 features none of their proprietary technologies. It’s a simple watch, built with the same quality and attention to detail that is a hallmark of Sinn but rather than pushing the envelope tech wise, adds new access into the beloved German made brand. Though US pricing has yet to be confirmed, we imagine it will parallel the more modern 556 model at $1,050.

Lastly is something we actually mentioned a few weeks ago when we went to the WatchBuys road show in NYC: Testaf certification. Testaf is the new standard certification for professional pilot’s watches. What does that mean? Well… it’s technical, but on the surface is a lot like diving standards, but for the air. Legibility, ability to withstand exceptional external forces and various safety precautions are all in place. I recommended checking out this article on Sinn’s own website for greater detail. Perhaps the most interesting thing about Testaf is that it is actually a project that was initiated and developed by Sinn in collaboration with the faculty of Aerospace Technology at the Aachen University of Applied Sciences. Hence why Sinn is the first brand with this certification, though they certainly wont be the last (in fact we know of some others already).
