·Hello,
I got a question regarding the manual winding of the Globemaster : can you damage the mouvement if you wind it manually while the mouvement is fully charged ? Does it have a safety feature to prevent it ?
I find it hard to manually wind my Globemaster but I though it was because it was already fully charged... Am I right ? I don't want to damage the mouvement obviously.
Hi @Gogarty,
No, I don’t think you can over-wind your Globemaster. If you keep on winding and hold the watch to your ear you will hear a sort of clicking sound which I believe is the mainspring slipping inside on of the twin barrels. That’s not something that you should do for hours on end but your not going to break your Globemaster that way.
If your Globemaster has been sat in a drawer unused for many days and has stopped running you will find that initial winding is very light. As you keep going it will become progressively harder to turn the crown until both springs are fully wound, but the crown will not stop rotating like on a Speedmaster Pro for example.
For comparison purposes a manual wind Speedmaster (caliber 861) will need about 35 turns of the crown between thumb and forefinger from fully unwound to the crown stopping dead. The twin-barrel 8900 in your Globemaster will need about 50 turns before you hear that tell-tale click. A further 10 turns and it will click again. Obviously you might get different numbers than I did depending on how far you run the crown between your fingers, but the comparison is still valid.
If you ask @Archer nicely I’m sure you will get a more robust explanation and generally fascinating answer.
I wish you many trouble-free years of enjoyment with your GM.
Cheers
