Non existent for my wife's 1925 watch, they simply said we don't service the old watches any more. Great service!, I won't bother to buy a new watch from this Company then.
by the same merit you're saying if you walked into a Ford Dealership with a 1925 Model-T, you'd kick off because they didn't have the ability to replace parts and service it?
They probably offer one of the best repair and servicing of all the major brands. With a 1926 watch though, you probably need to look on VRF (vintage Rolex forum) for some service recommendations.
