The Diastar has a pretty unique crystal, which is divided into 9 sections, with the outer sections dropping off the middle at an angle. A very appealing, but maybe slightly confusing design when trying to tell the time 😉
There is a lot of gunk around the winding stem – looks almost as if someone used silicone on there… good for a shower cubicle, not so good on a watch 😉
Same gunk where the case back gasket should be. Always interesting to see what other people get up to!
Gunk alert on the case back, too.
I clean out the whole mess, put in a new O-ring gasket, and close the case.
