Historical Perspectives: (Possibly) The World's First Perpetual Calendar Wristwatch, From Breguet, Revisited On Leap Day 2016
Here is the "Dollfus" Perpetual Calendar, nicknamed after its original owner – sold at auction in 2011, and not seen in public since.  Though it's well known in enthusiast circles both by name and reputation, we thought today – Leap Day – would be a great opportunity to look back at this historic watch - the first perpetual calendar wristwatch. When this particular watch was first sold, the price to the new owner, Mr. Jean Dollfus, was 11,000 Swiss Francs.  It was a lot of money then, and today it would be considerably more, but even the inflation adjusted price pales in comparison to what it fetched at auction at Christie's, in 2011: $475,618.  It's obviously an enormous sum of money, but the price becomes easier to understand, when you understand what the watch represents. 1 OF 4 It's quite simply one of the most important vintage wristwatches ever made by Breguet, and perhaps the single most important perpetual

HELP!! Brand New Orbita Sparta Two Open Lithium Problem
Just 2 hours into getting my brand new Sparta Two Open Lithium and spending some time testing it, I discovered that the left winder does not operate on the extended cycle when the switch is set to 15. It turns at 10 mins intervals even when the switch is set to 15.The right winder is fine though. I've checked and double checked, turned the unit on and off, removed and re-inserted the batteries and to my dismay it still happens.I'm located in Singapore and I purchased my Sparta from the Watch Prince and had it shipped here from the US.What should I do now? UPDATE: When the left winder is set to 10, it turns every minute! I can't believe this :(

strange to see photos of PP 5711 and AP 15202
I absolutely love both models but when you see pics of both you have a hard time believing that the AP is 0,2 mm thinner, as it looks, on pics much thicker to me, anyone have the same feeling about this?
