This is an academic question for the time being, as I bought my Seamaster 300M brand new around a month ago, but I am intrigued to know when I will know that it needs servicing?

The AD told me it won’t need servicing for around 10 years. Do I just go by that date or will there be something obvious that will inform me otherwise?

Also, what factors will bring forward or extend the interval? Will wearing it more be better or worse for the watch, servicing wise?

 

Your watch will tell you when it needs to be serviced.

 

Very useful, thank you.

 

@Alex_TA is probably right. If it’s still running well in ten years get it serviced per the dealer’s suggestion.

But if it starts running too fast or too slow before then, well, get it serviced.

I know that you knew that, but this is a good opportunity for me to ask for photos of your watch!

 

1) if you had it serviced 5-10 years ago, it should get a service
2) if it ‘tells’ you it needs a service (and 1 applies)
3) if the service history is unknown

 

From new …….

Easy

Every 7 years.

If you want to dive or swim regularly with it get the seals changed and a pressure test every 2 years.

 

Here you go. Extremely chuffed with it.

 

Apologies, I did t put that I bought it brand new. Original post now duly amended. Thanks for the time responding, as the info still applies. Cheers.

 

It’s a Divers watch but, like many, I won’t be diving with it. In fact, I am unlikely to even swim with it, so will probably not replace the seals as regularly.

 

Lethargy. Dial appears pale. Raspy ticking. Movement oil incontinence.

 

These new models with the METAS certified master chronometer movements are so impressive that they will actually call you on your cell phone and remind you when a service is due. Actually, I would go wiith STANDY's advice. Sounds about right and it's what I would do.

 

probably service at 7 year intervals no later. Careful on the oils

 

No worries. I am thinking the same after reading around a bit more. 10 years sounds a touch too long in fairness.

 

The only watch in my collection that is serviced according to a schedule, is the one I wear the most. Even at that, it isn’t worn more than two months or so during a year, but it the closest I have to a daily driver. That is my 1989 Rolex Date-Just with the calibre 3135 movement. In the 30 years I’ve had it, I have serviced it 5 times, and replaced the mainspring, once. This watch consistently performs within 15 to 20 seconds per month. When it no longer runs that accurately, I don’t move the regulators (there are 4 meantime screws on this free-sprung balance wheel), I just condition it. I serviced it most recently about one month ago. This time, I did a small regulation on it after the service, and that was about three weeks ago. As of today, it is 16-seconds slow in three weeks. I’ll move regulator and re-set it today. This watch tells me when a service is due.

 

I'm relatively new to Omega as well, but from what I've read, Omega replaces whatever needs replacing and your cost is the same regardless, so there is no real incentive to do preventative maintenance and prevent wear. For that reason, just send it in when it starts acting funny, that's what I'm going to do.

I emailed Omega asking about servicing my 2021 300M and this was their response:

Your OMEGA watch was conceived to stand the test of time. It will accompany you through life and continue to give you the time with beauty and precision if it regularly receives the best care. The service frequency depends on the use of the watch and the environment in which it is worn. The water resistance can, for example be affected by the ageing of the gaskets or by an accidental shock. Therefore, we recommend that you have the water resistance checked once a year and a complete service performed every 5 to 8 years. Your OMEGA boutique or authorised service centre will be happy to take care of your watch and answer your questions.

 

I got a timegrapher. My watchmaker says that I should consider a service, if the amplitude drops significantly from the value just after last service.
