I have a Seiko watch, purchased in 1992. Recently, a battery replacement was the last straw for the ageing seals, and moisture got in. My local watch mender could not locate a supply of seals.
I browsed websites, looked in windows and shops, but cannot find a similar replacement. Like cars, everything has grown. I do not need a clock on my wrist, but I do want day and date, which does not seem to exist in the normal sizes.
Hopeful, I emailed Seiko. They declared that they had seals, so I sent it to them.
Seiko examined it, and quoted for a service. Their communication did not mention seals.
My reply emphasised the need for seals. They accepted that and went ahead with the repair, including a service. They recommend a service every 5 years, so perhaps overdue,(31 years) and shouldn't do any harm.
Now the annoying bit. Just received an email, job done, invoice attached. Invoice states service. No mention of seals, not in work done, or parts used.
It used to annoy me when garages I worked at would do a service on a car, and request a customer bring it back for the other work. Yet the other work was the reason for their visit, the service was added when recommended by the garage. Priorities!
I await their reply to my clarification question.
