My WM, Lionel, just finished a movement transplant; the new Tissot auto cal 2481 (a shared movement project with Omega, early '70s) works like a charm. Just push the crown to set the date!
I'm not a Rolex fan at all, but this one I love! I don't believe I've ever seen one this handsome... Is there a reference number? ... never thought I'd say this, but 'Dibs on the Rolex'!
