Omega 3330 Speedmaster Hand sizes ?

[hofnerpres]

I hate doing chronographs without a spare sweep second hand. Modern factories seem to delight in putting these on with a pile driver. The last one left the tube on the shaft and it was amusing. Any of you lot know what the sizes are for the 3330 ? Needless to say these latest Swatch movements are getting hard to find information or parts. The car guys were forced to give out their information and parts but we got squashed.

The Valjoux 7753 are 0.18 so I'd expect these would be the same.

Thanks Andy. The 0.18 Valjoux size is for the subdial hands. My concern is to have a spare sweep seconds hand which might well be the usual Valjoux 0.25 mm.  - They can break.

Sorry I misread the sweep second part but yes I expect it's 0.25 but at that size you should be able to measure it.

No worries Andy. As expected it took some careful levering but the hands came off straight and measured at Valjoux standard 0.25  1.20 and 0.18 shaft sizes. I'm looking at selling a watch and investing in one of those nice Horotec hand removal gadgets. Too much risk and  mental stress involved pulling these chrono hands. Neil.
