I very recently got a pre-bond 40mm automatic that I love. However, it is losing around 6-7 seconds per day. It probably hadn’t ran in a decade before I got it. So, some info I have seen says let it run for a few weeks and it will improve. Is this right? If it does not improve, can I have it serviced to correct?
Thanks for the input.

 

Sounds like it definitely needs a service, in fact you might even damage it if you run it for long without. If you give us an idea of your location someone should be able to recommend a knowledgeable watchmaker.
In the meantime, how about a photo of your pre bond?

 

It’s worth pointing out that minus 6-7 secs/day isn’t that bad for a vintage mechanical watch. Ideally most people would want it to gain rather than lose time but it’s still ok from a timekeeping perspective.

Obviosuly the fact it hasn’t been serviced in years means it needs a service regardless. You however find that timekeeping afterwards is comparable to now.
