Hi,
I have three Seiko watches,
a SKX007 with 7S26, a Monster with 4R36, a SARB033 with 6R15.
7S26 has an incredible amplitude of 310°
4R36 has a normal amplitude of 280°
6R15 has a low amplitude of 250°
When fully wounded the 6R15 goes up to 280° but after five or ten minutes the ampltidue goes down to 250° when face up.
The watch is pretty new, is this something I should worry about? Should I service my watch? The watch has been worned for at max 6 months and it has 1 years of life, worned every 15 days at least.
Thanks
