I know this particular model has been well covered, but as someone who frequently searches forums for ages looking every possible shot before making a decision...
I purchased last week 2nd hand after failing to sign up for either of the Watchbuys open calls.
It arrived & I have to say I'm pretty pleased.
The case is relatively simple, but there are some lug bevels to keep interest high. I would have preferred some brushing, especially along the sides, but I guess polished will do for now.
I don't time watches, so I can't speak to accuracy. But it's keeping pace with the others in my winder.
When it was announced back in the spring I was immediately attracted to the simple dial, countdown timer & relatively modest sizing. In all regards I'd say Sinn hit the mark.
You'll notice mine is on a different strap. I prefer tapering & also thought a slightly less dark color would work well. Luckily I had a custom that fit the bill.
