Breguet

Today I heard from a usually very well informed AD the following. Since some time Breguet is improving their movements in two ways: 1) replacing parts with silicon substitutes and 2) rasing the beat per hour. Further, they slowly upgrade movements in deal... 

Yes, the upgrades are a reality. Thees models should all be out by fall 2010 at the dealers so they are worth waiting for. Silicon balances and higher beating rate are big improvements...

Do you happen to know wich models are involved with the upgrade program? Something else. I see you are from India. I think it is mostly rather hot out there, right? I have heard about special Breguet straps for tropical use for dress watches; leather outs...
