I bought my Seamaster cal 560 aprox 1.5 years ago. I don't know the service history. I open the watch and see blue ink marking (see picture attached) inside the case but I can't figure out what it means. I assume it is related to service date. May somebody help me, based on marking, when was the my watch serviced.
Thank you.

 

July 26th. 2005??

 

Thank you, Foo2rama. I have the same tought. What do you think about other numbers at the bottom?

 

Only the person who serviced it knows what those numbers mean. They could be dates, work order or invoice numbers, or some other code.

 

Thank you, Archer. I'll assume the service date 07.26.2005. This means I need to service it ASAP. Watch is working fine but possibility of 14 years w/o service is a concern.

 

Do you have a recommendation for service shop?

 

I live in Windsor, Ontario, Canada and I don't have problem sending it anywhere in USA/Canada.

 

Looks to me like it was done by a chimpanzee based on those markings. Give us an idea of your general geographic area. Maybe we can suggest someone.
