It often ends up in a yes or no debate. I offer a more blended answer. Qouting myself from an old thread - my philosopy =
When it comes to strategy of using vintage watches/modern watches I anwered in another thread - about using watches in water:
"(It) Depends.
(dive watches)
Modern watch (but outside warranty time) that has been recently pressure tested/serviced under your ownership = go
Modern watch (but outside warranty time) that is said (by seller) to be recently pressure tested/serviced = no go
Vintage watch, which already have had parts changed (making it non original and not period correct) and when service parts are still available and if it is recently pressure tested = go
Vintage watch in strict original state/period correct and/or where parts are no longer available = no go
For instance - my Seamaster 1000m has a service dial and bezel. Serviced last year and parts available = go
My old but recently serviced Seadweller = go
My Seiko 6105 (not serviced and original parts not available), Zenith 1000m (no parts), Certina DS-2 SuperPH1000 (no parts) = no go
Value is less important than these parameters (Seiko vs Seamaster 1000)"
