Hi there everyone,
Being my first post, and thread on Watch Talk I thought it would be fitting to ask for info on the following topic. Who was the 'first' to achieve various feats in watchmaking (ie first company to use certain case materials, chornographs, GMT, tachymeter, self winding wrist watches etc etc)? When was this feat achieved?
There's always claims from different companies so let's try to set the record straight!
