Late last week, German tool watch uber brand Sinn launched a handful of new models including a brand new line, the 105. Functioning as a sort of modernization of the format and aesthetic established by the more vintage-effect 104, the new 105 series feels fresh and includes four launch models spanning both a day/date and a UTC complication with either a black or a white dial with a dash of orange accent coloring.
Both the 105 St Sa (that is the day/date model, with a “W” added for the white version) and the 105 St Sa UTC are 41mm wide, 11.9mm thick, and 47.4mm lug to lug. Without a strap or bracelet fitted, weight is 73 grams, and buyers will be able to choose between a black leather (with orange accent stitching) strap, a Sinn rubber strap, or a full steel bracelet. Both specifications will come with a hardened bi-directional ratcheting bezel, with the 105 sporting a twin-scale bezel design that shows both a 12-hour scale (for a second time-zone) and an elapsed time scale. For the 105 UTC (which uses an independent 24-hour hand), the bezel shows a 24-hour scale to connect with the GMT/UTC hand.
Both iterations of the 105 use nicely balanced and very legible dial designs that place the date (day/date on the 105 St Sa) at six o’clock, and I rather like the stacked execution of the day and date feature for the 105 St Sa (shown above left). As is common to a lot of Sinn’s designs, dial text is kept at the absolute minimum, and the 105 looks rugged, modern, and undeniably Sinn-ish.
Both models make use of automatic Sellita movements, with the day/date execution employing the SW 220-1 and the UTC-spec opting for the SW 330-1. Both movements offer around 40 hours of power reserve, tick at 4 Hz, and can be seen via a display caseback.
As we’ve come to expect of Sinn, the 105 ticks all of the common tool-watch boxes, with 200 meters of water resistance, sapphire crystals, anti-magnetism to DIN 8309, water-resistance to DIN 8310, low-pressure resistance, and a screw-down crown.
While it’s not exactly surprising to see Sinn continue to operate in this size range after the apparent success of the 41mm U50 from earlier this year, it is exciting to see more from the brand at this size and price point. I also like that the 105 offers a break from the endless vintage-effect styling that has claimed much of the sport watch market (for both good and bad, I think).
Pricing for the 105 starts at $ 1,560 for the 105 St Sa (in black or white) on a leather strap and tops out at $ 1,840 on the steel bracelet. Likewise, pricing for the 105 St Sa UTC (in black or white) starts at $ 1,830 and tops out at $ 2,110. Certainly not without competition (more by the day, really), the Sinn 105 establishes a fresh new line for the brand that manages to feel distinct from its siblings while also being born of Sinn’s ever-specific perspective on sports watches.
