I have a datejust from the mid 1960's that's losing about 5 seconds a day. Is it worth taking it in for a service, or is this an acceptable loss for a watch this age? thank you for your time. Sincerely, Kevin
If never, well, it is time to give it a nice treatment. If more than 10 yeqrs, same answer. And if the Service is unknown, it would be more prudent to send it for a service. Best, Nicolas
