Omega's policy is to have these sent back to the factory in most cases...from the technical guide for the Cal. 3600...
"Due to the complexity of the product and the need for special tools, work on the watch is strictly forbidden (exception: rate adjustments). Watches showing signs of a technical defect must be returned to the Omega after-sales service department. The only exception to this is service centers with specialists trained by Omega, and in possession of the special tools required."
Cheers, Al
