7A28 Seiko help
Dear crunchies,
Here my favorite seiko twins in my collection, sadly they are in need of help!
Both have a problem with the chrono, on the left the big seconds hand stops just before 12 when being reset and on the right theres a similar problem with the small minutes hand.
Also on the right the minute hand actually doesn't move at all when the chrono is activated, only when reset it moves and stops at random.
Both can manually easily reset, still its bothering me.
I brought them both to a watchmaker for a service 3 times and they work like a charm for several days until the problem returns.
Does anyone know what the problem is? Watchmaker informed me that the watches look almost like new from the inside, also they keep perfect time.
If maybe someone has an idea what causes this im probably gonna change the watchmaker and maybe can steer him in the right direction
