Four New Audemars Piguet Royal Oak Perpetual Calendar Watches For 2015
The perpetual calendar is among the most highly regarded complications in?horology ¨C and?with good reason. The way its all-mechanical brain knows the lengths of the months throughout the years and makes the date display jump from the 28, 29, 30 or 31st day to the?1st all by itself, even in leap years, is?genuinely amazing to all watch enthusiasts ¨C while its exact workings?is understood by much fewer. The four new Audemars Piguet Royal Oak Perpetual Calendar watches for 2015 bring back the terrific looks of the original "RO QP" ¨C the Royal Oak Quenti¨¨me Perpetual ¨C albeit at a slightly larger size.Originally designed?in 1981, the Audemars Piguet Royal Oak Perpetual Calendar to this day, remains one?of the most timelessly beautiful dress watches with this complication. What's new in 2015 is that the "new" models, by the reference?26574OR.OO.1220, are 2 millimeter wider, coming in at 41 millimeters now (that is, excluding the crown, as always).Two versions in steel and two in pink gold,

Just getting started
A couple months ago if someone told me they collected watches I would have thought that sounds silly. What a difference a couple watches can make. Now I feel like I'm hooked on a new addiction. I purchased an Invicta Pro Diver as the "deal of the day" on Amazon. Next thing you know the home shopping networks (which I never watch) comes on with all the watches. I ordered 2 more Invicta's. I found an old Seiko I had years ago and took it in to have repaired so now I have 4. Funny part is I can't wait to add another piece to my collection. In reading on here there seems to be some negativity towards Invicta and at first I was kind of bummed like I made a bad purchase. After some thinking at the end of the day I like how they look and have performed well for the short period of time I have had them. If nothing else they did get me started on what seems to be a very fun hobby. I am looking to step up a little on my next purchase. Maybe the $500 to $700 range. I don't think I will get anothe

There were drawbacks however - lubrication was one issue. Also, the physics involved with such a high rate and rotational mass caused them to reduce the size of the balance wheel, which reversed the trend in their automatic calibers up until this point.

Speedmaster 9300
Received the new 9300 Speedmaster. It does not sit as high on the wrist as some commentators opined. It is actually very comfortable on the stainless steel. Be careful when taking the screws out to size the bracelet as they are very small, and both sides have to be taken out to remove the sleeve. Very legible dial, and supposedly water resistant down to 330 feet for whomever was asking the question about swimming in their Speedy, although the owner's manual suggests rinsing it off if you have been in Seawater, and not using the chrono buttons under water. My first day, so too soon to tell, particularly for a Rolex guy, but this one seems like a terrific watch right out of the box.
