Historical Perspectives: (Possibly) The World's First Perpetual Calendar Wristwatch, From Bregue
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

Took the PLUNGE
I too have now joined the ranks of SMP owners. I just purchased the 2252.50. I choose it because the 2254.50 looked HUGE on my wrist. I'm expecting delivery any day. My jeweler told me that between the time I was quoted a price and the time the watch was ordered there was a price increase. The wouldn't tell how much it increased and did not pass the increase on to me. Does any know how much the Omega increase was? Also I read where the 2008 version of said watch may have upgraded works. I can I check the movement that is in my watch?

Auction find
I have started a couple of threads in other forums about watches I bought yesterday. I bought a box of watches at an estate auction to get a Railroad Approved Accutron that was in the box. Now I'm having a wonderful time going through the rest of the watches to see what I have, what works etc. I shook this one a couple of times and it took off running upon which my wife claimed it and took off with it. Can anybody give me some idea what I have, how old it may be, is it a lady's watch or a man's watch etc. Any help will be appreciated.

Watch on ebay
I have been reading in these forums for quite awhile. I have noticed that many of you enjoy vintage watches. Anyway, tonight I was looking on ebay an found an older Elgin Sportsman automatic wind watch. The auction ends in 11 hours. The bid is at about $25 with shipping. What is a decent price for this watch? Does anyone know?

Cost of materials?
Have you ever wondered how much the materials cost in a high end watch...as a percentage of its price?This came up after I noticed that watches with solid gold alloy cases are FAR more expensive by thousands of dollars...in spite of the fact that the actual gold content might only be an additional $800.00.Strangely enough, there don't seem to be any solid brass cases available. An alloy of 74% Copper, 25% Zinc and 1% Tin would have a gold like colour and some corrosion resistance.
