Ceramic Ball Bearings
Hi Peter,
May I know whether GP is using any ceramic ball bearings on their WWTC chronograph watches ?
I bought a SS WW.TC a few years back (year 2003 ?) but I do not think it is fitted with these bearings and think it is fitted with a GP033C0 calibre.
If they are not, do you think it is possible to make an upgrade of using these bearings on my current watch since these bearings are said to be better ?
Pardon me for my limited knowledge.
Hope you can enlighten me.
Thank you.
Regards,
Ken
