Montblanc Nicolas Rieussec Chronograph Silicon Escapement
Montblanc presents the chronograph in its seminal form and makes it state of the art with a silicon escapement. Nicolas Rieussec registered the world's first chronograph for a patent on in 1822. That first “timewriter” is reflected here with disks that turn beneath motionless hands, as the chronograph’s inventor intended. Rieussec sought the ultimate in accuracy and reliability, and this limited edition is true to that history with a movement in which the lever and escape wheel are fashioned from silicon. This piece will please those who love history as well as those who want the latest in technical innovation. Like microprocessors for computers, certain movement components can be etched from paper-thin silicon wafers. The DRIE (Deep Reactive Ion Etching) method combined with silicon’s inherent properties offer optimal conditions for manufacturing tiny movement components. Silicon is 60% harder and 70% lighter than steel, highly resistant to corrosion and entire

Advice on gold audemar piguet watch please
Hello,newbie here. I'm hoping some one may be able to help. I inherited from my dad a Audemar Piguet gold bracelet watch (attached pics). I remember it from the seventys when my dad would shake it to wind it up. It's now just left in a draw at home so I've decided to sell. Not sure of it's value or where best to sell it. I took it to a local gold merchant geezer who offered me 700 quid but thought it would be best to seek further expert opinions. Any advice I really would be grateful for.Thanks in advance.

My new 523
I have now owned my watch for a week and have decided that it is time for a new strap. I LOVE the Brown Aligator strap that came with it. I am looking at the Black Aligator strap with the deployment buckle. I have found this strap on Watch Band Source and it says it is OEM. Has anyone purchased a strap form them and is it really OEM? Given that they are selling it for $289.95 it seems lower than anything that I have seen in the OEM market. Thanks.

Started out a couple weeks ago with the new Radiomir 572. Last week I attended a Panerai evening event at a local AD. Today this arrived, the Luminor 372. They make a great pair. And I'm already thinking about going gold! Just a thought for now.
