Verified Owner Comments: My concern prior to purchasing the 105 was it's sizing. Generally, on my slightly over 6.5 wrist...40mm is as large as I like to go (without looking like I'm wearing Daddy's watch) this one is 41mm. But with a lug to lug width of 46.5mm, it sits perfectly coupled with the 11.9mm height, its and easy wear.
The bracelet secures the watch exceptionally, eliminating the necessity of having to re-position with every turn of the wrist, and sizing/removing links was not a problem whatsoever (even for my non-mechanically inclined brain)...excellent design in developing a very secure and comfortable linkage system. My other hope was for a well regulated movement.
Plunking down $2K for a Sellita 220...I wasn't so sure. But Sinn has managed to get this piece to within 3-5 secs./day (fast), with consistency. So...more than satisfactory in my opinion for the price-point. There's still a place in my heart for my Oris 65, but she's always been 10-12 seconds slow. (Also a Sellita movement.) Other Sinn owners have reported similar performance in their watch movements. An added note...I don't prefer automatic self winders, as I don't like the 'feel' and/or the sound of the flywheel moving.
This one is virtually un-noticeable when the watch is being worn so no complaints there. Another reviewer reported difficulty reading the face at different angles, secondary to the white dial. That, has not been my experience as the hour, minute and second hands are clearly in contrast to the white facing. And for night reading, I've been impressed with the duration of luminescence (as usually, blue varieties of lume are not quite as bright or lasting as the green). This one however, gives off enough light to be able to read the time throughout the night.
Considering this, I don't think most buyers would be put off by the fact that the markers are blue rather than the product description reading 'green'. I really think you'd be hard pressed to find a better, more accurate tool watch at this price-point. This one's a wear-er and I believe would hold up under the daily rigors of first responders, active sportsmen, and desk jockeys alike.
"A modern classic?"
Verified Owner Comments: This timepiece has a clean, almost Bauhaus style, look and feel. The dial is completely matte, and the white reduces the visual size of it in combination with the contrasting black bezel.
The blasted metal surfaces are expertly done, and the completely matte finish works exceptionally well in a business casual environment.
I chose the day/date version over the UTC because I felt the Sellita SW 330-1 movement is not quite suited to GMT/UTC functionality.
The SW 220-1 in this one though is a workhorse, and mine is keeping +2s per day out of the box! It is a wonderful watch that works well in the everyday wear slot. Now to try some alternate straps...
"A Little White Sinn"
Verified Owner Comments: Love the modern dial design of this watch. Need more watches with a modern look, rather than only vintage designs. Great fit on my 6.5 inch wrist. Yes, the hands can be difficult to see in certain lighting and angles, but I love white dial watches and can live with that. Lume not the brightest, but it does last through the night. Is keep excellent time. Highly recommend.
"On wrist every day since it arrived"
Verified Owner Comments: The 105 St Sa brought me back everyday until I finally pulled the trigger. The bracelet is comfortable, the bezel rotation is solid and satisfying, the lume is pleasant (blue-er tint?), the vertical day/date is a nice change, and the time has been right on. I've worn it every day since it arrived two+ weeks ago.
I keep coming back to Sinn because they're comfortable, no frills timekeepers.
