SpeedMaster needs a service..

Greetings, my first post.My 35105000 will stop running after 15, 20 minutes after a full wind. Is this a common problem with this model?
Any advice on a service, and cost will be welcome.
I live in East TN USA
many thanks

I've not heard of it before, but it suggests to me (not a watchmaker) that you have a broken mainspring. The mainspring on mine was found to have a developing fracture when it was serviced.

You could send it to Omega and price should be on their website. I sent mine to an independent in the UK and in 2016 the invoice was for £379, or somewhat lower than Omega, but the watch had no visible issues, just a lack of service information.
