This new version was the caliber A display back version of the was made as well, which swapped out the Delrin plastic brake lever of the for a metal one. This was the caliber A side-by-side comparison does reveal some subtle visible differences, although the most dramatic differences between the two calibers are functional rather than cosmetic. The also has some visible differences that are clues that you're looking at a Take a look at the balance cock the metal projection that acts as the support for the upper balance pivot.
The has a standard regulator system, while the does not; that's because the has a free-sprung adjustable mass balance, in which rate is regulated with timing weights on the balance itself.
The timing weights are a little hard to spot, but if you've got good eyesight and maybe a loupe , they're there all right. They're in the form of screws, located on the rim of the balance between the spokes — above, you can see one at about on the balance rim. The level of finish is almost the same between the and the , but it's not identical.
Both have beveled bridges and nicely finished countersinks for the jewels, but one pretty subtle difference between the two is that the bridge for the chronograph intermediate wheel — above, at about , between the driving wheel on the left and the chronograph seconds wheel in the center — has anglage in the , and it doesn't in the I spent a lot of time staring at the caliber over the week we had it, and I thought once or twice that the anglage on the was maybe a hair wider, but I wouldn't swear to it under oath.
The finish on the display-back caliber , on the other hand, looks virtually identical to the Should I get some flak for dwelling on the movement?
I obviously don't think so. My HODINKEE colleagues tease me every once in a while for being such a gearhead, but that's to be expected since taste as refined as mine doesn't come along every day. But I also think there's a good argument to be made for understanding the technical and aesthetic evolution of the as a path to better appreciation of the watch. The Moonwatch is a beautiful wristwatch, but it's also a tool which for much of its history has been expected to put up with hard knocks and come through unscathed, and the movements inside have a lot to do with that.
Knowing something about how the descended from the — and it is a direct line of descent both technically and aesthetically — adds an awful lot to the emotional experience of wearing the Moonwatch Master Chronometer and, in my case at least, goes a long way towards relieving where-the-hell's-my-salt-lick level anxiety.
Okay, I didn't but I would have. Granted, when it comes to the Moonwatch, I'm like Ron Weasley after Romilda Vane hits him with the love potion — googly-eyed, uncritical, adoring; a moping mess of a fanboy. Still, though, I was prepared to find fault with the if I could, usurper though it might be. As it turns out, however, I got something that was less an overthrower of the Moonwatch from its throne than a subtle but marked improvement on almost every level — Daniel Craig's James Bond after Vesper Lynde puts him in a suit that actually fits.
The outgoing Moonwatch is never going to lose its appeal. It was the first good Swiss watch I ever owned, it would probably be the last I ever get rid of if I had to sell off my worldly goods to buy a new crutch for Tiny Tim, and I will love it until the day I shuffle off this mortal coil and join the choir invisible. Too little change and the watch becomes an anachronism; too much, and he risks the righteous wrath of the Speedy-collecting community.
Hence the biggest changes are under the bonnet: the new Calibre replaces the , itself descended from the which in turn can trace its lineage back to the Lemania 27 CHRO C12 chronograph calibre of Strings of reference numbers are what get Speedy-freaks out of bed in the morning.
Around 50 per cent of the components are new, and not all relate directly to Master Chronometer certification; for instance, the mainspring staff has been slimmed down to accommodate a little more spring, which in turn adds a further two hours to the power reserve.
Omega is very proud of those two hours. When it comes to case and dial it is even harder to spot changes. While genuflecting at the altar of such barely visible but oh-so-important design details as the position of the dot over 90 on the bezel, Aeschlimann has successfully avoided clumsy retro touches.
And thanks to a declivity beneath the hour markers there is now 75 per cent more luminous material that lasts three times longer at twice the intensity. History can only take you so far.

Especially for Speedmaster aficionados and fans of historical detail, the famous dot over 90 DON and a dot diagonal to 70 are included on the anodised aluminium bezel ring.
Created with a new design, the bracelet clasp features a polished OMEGA logo on a satin-finished cover. Beautifully refined with a width of 15mm, it also includes two polished pushers in a new oval shape. There are four eye-catching models in steel that make up the Speedmaster Moonwatch Master Chronometer collection.
The hesalite glass models can be chosen on a nylon fabric strap, or a fully-brushed stainless steel bracelet. The sapphire crystal models can be selected on a leather strap or a stainless steel bracelet with polished and brushed links. It took 4 years to produce a calibre that could achieve Master Chronometer certification, while also matching the dimensions of the previous Moonwatch movement - the The new calibre has done exactly that, while improving the power reserve, chronometric performance and magnetic resistance.
Taking the levels of luxury into a higher stratosphere, a collection of 18K gold models is also on offer. A year after, NASA began their search for a reliable timepiece that astronauts can use in space and can serve as the official watch of the program. After a series of torturous tests done on the watches, only the Omega chronograph passed.
It became the official watch of NASA astronauts, and remains so until today. The Omega Speedmaster ref It eventually made its way on the Moon when Eugene Cernan wore it during the Apollo 17 mission of Now we get to the reference that turned the Speedmaster into the Moonwatch — the reference Neil Armstrong, the first man to step on the Moon, was also provided with this timepiece, but legend has it that it stayed on board of the Lunar Module.
