the springs in question, some are american, some are swiss, if I take

You don't find them different? Old blued springs are not as
"springy", IYKWIM. Isn't there a risk of having too strong a
spring?
yes they can be a bit stronger, but I just fit a slightly weaker spring
if the amplitude of the balance is so great that it risks overbanking,
this where the Generale Ressorts SA of Biemme Suisse little blue
handbook GR2 1974 edition comes into it's own, it lists every spring
they made, you can easily go down the list for a stronger or weaker
spring and the calibre that it fits
not sure if this is the company that was taken over by swatch.
AIFAIK, they are still independent, part of the Acrotec group.
Plastic instead of glass? Remind me to never buy an antique
watch from you!
;-)
Seriously, though: I do hope you inform the proud owners that
plastic "glass" or plastic dials can significantly reduce the
value of their piece.
well they do know, plus I simply cannot buy the thin hunter crystals in
the diameter or heights needed, provided the bezel is in good condition
you can fit the very thin plexi and adjust the height by fitting a
slightly larger or smaller diameter plexi, this is where the Robur glass
tool comes into it's own.
I guess we're lucky over here; I can still find old glass for
most any watch.
when I first started in the trade some 40 odd years ago, there were at
least 6 general parts suppliers in Sydney, now there is one and there
stock is going down on the older stuff, one supplier that was taken over
in the 80s still had a vast array of pocket watch crystals, but he had
been around since the ark, don't know what happened to that, old watches
weren't the thing then, those new fangle quartz took over ;)
In a way, it is slightly odd that there is no manufacturer out
there still making these. AFter all, there are still makers of
buggy whips, manufacturers of valves and producers of vinyl
records. The demand may be small, but in this day and age of the
internet, I would have thought it quite feasible to have a
globally operating company for such specialised products.
far as I am concerned fitting one of these very thin plexis into a
hunting case doesn't take the value away from the watch, and I would
rather have something there to protect the hands and dial, because no
matter how many times you tell them not to the customer will finger the
hands and dial.
It's really a question of originality. You wouldn't fit any old
crown on a wristwatch, either, would you?
