Currently acquired a used Sinn 157.
My first Sinn (and actually my first ever watch) with Lemania 5100.
Absolutely loving it so far. Goes pretty good - losing around 15 sec/day. Considering that the service history is unknown.
However, as it being my first 157, and 5100, I have a couple of questions:
- the top pusher (start/stop) is very stiff and really hard to push. The bottom pusher (reset) is good. Is this normal?
- want to remove the movement. pulled the crown but the movement doesn't move and I don't see any screws holding it. What is holding the movement?
