nothing wrong with clock oils. as far as new engine oils, there are no corosives for brass or bronze. the old "non deturgent" "mineral oils" were replaced by synthetic motor oil. a great improvement ! i was working for standard oil when the "multi - viscosity" oil came out. many tests were were made. don't use it on watches. vin

not mineral oil or whale oil, synthetic oil, multi additives and multi viscosity. that is the point. though, i would like to get some whale oil. vin

O. H.; no, tranny oil is not a lube. i think engine oil is quite usable on clocks, not watches. V.

" stem fallout", can cause many odd problems, like " upset crown gear". could you have determined WHY? vin

looks interesting, try it out, at the worst - it might just be home made. cheers, vin

welcome to the forum. vin

at last; !, multi. visc. engine oil is reconized ! i don't use Tranny oil because, it is hydrolic oil, not engine oil. vin

i think we have been there before. no offense meant. in my exsperience with the push pin or the screw; if you mess up its "dial off" at least. the experts usually don't have this probem. vin p.s. if the dial pin retaining set screws are "rusted it", - another story.

there is watch repair school in Finnland, but they refuse to speak English.

welcome to the load of new members! remember; even if you are [or were] a heavy equipment, [driver or mech. or both]; the chances of losing any fingers on watch repair, are slight. vin

good explanation. and referance. vin

the art of tinning uses a product called "tinners fluid" at one time, you could buy it or make it. vin

since "trench watch" means WW - 1. not many left in circulation AND not many "military marked" . there are copys - very common. vin

the two part case wrist watch is not to common. some very good watches were made that way ( girard perregaux ) the problem is , with age, they tend to "fall apart". (no longer a press fit) after service, should one glue the two parts together ?

the Chelsea bulkhead clocks have a pallet escapment that could be bought for $50 U.S.. no longer available, navy went to quartz and battery. vin
