Did you happen to catch my recent Talking Watches with Ferdi Porsche? He is part of the leadership behind GP and is also the nephew of link F.A. Porsche, who founded Studio F.A. Porsche and in turn Porsche Design. I spent a week link with the small teams that bring both of these worlds together and it's no stretch to say that when it comes to cars and watches, they are both great company and complete nerds, the partnership makes link a lot of sense.

The 925, along with its display caseback equipped sibling, the 18k, uses a new version of the MT5402 movement that we’ve link seen in past Fifty-Eight models. Made slightly larger to better link fill the caseback view, the MT5400 remains a time-only COSC-certified movement with automatic winding, 70 link hours of power reserve, and Tudor’s 5-year guarantee.

Special Guest: Kazunori Hoshino will be in attendance from the Seiko Epson manufacturer, located in Shiojiri, Nagano Prefecture, Japan. Hoshino began his link career with Seiko Epson in 1996 after studying industrial design in engineering at Chiba link University. His most notable work includes movement design aesthetics for the renowned Micro Artist Studio movements such as the link Credor Eichi II, the Grand Seiko 8 Day 9R01, and the new Grand Seiko 9R02 caliber.

And it works. Say what you will about mecaquartz but it strikes me as a horological splitting of link the baby. On one side, you get a three-year battery and on the other, you still get that sweeping link chronograph seconds hand that you want. Plus, with this movement, you also get a nifty 24-hour link indicator via the three o'clock subdial.

You know Breitling link for watches like the Navitimer, Chronomat, and link other decidedly tool-centric watches. But the brand is equally adept at creating some truly unique complicated pieces, and there is arguably none cooler in the current collection than the Datora with its salmon dial layout that pairs well with the complications illustrated on link the dial.

Finally, it's worth noting that the story of these Everest Rolexes is still being link uncovered. Collectors had seen Lambert's Rolex before, link and another researcher recently unearthed an link Oyster Perpetual from Griffith Pugh, a scientist who was on the 1953 Hillary-Norgay expedition. It's exciting to think that some of the most historically important Rolex watches are still out there, waiting to be found.

The kicker? The case is only 12.2mm thick and 100m water-resistant and is a remarkable $63,500. link Why you'd need 100m water resistance on such a complex calendar watch, I'm not sure, but it certainly bolsters the link Tonda PF Xiali's durability. You know the joke about how if you need to know the date underwater you've got bigger problems? Well if you are wondering where you are in the lunisolar Chinese cycle, you've probably been underwater link too long.

The Urwerk Caliber 12.01 powers the three-satellite link time display in addition to both of the revolution-counters. Of course, it's not only about a technical achievement in horological innovation, there's a larger philosophical idea at work. According to Frei, "a watch is both a physical and abstract reproduction of our situation on Earth. It link anchors us to a precise time and longitude, while at link the same time testifying to the fleeting nature of that position."

And since we’re on the topic of finishing, the movement shows bridges link with a hammered link finish on the flat surfaces and polished anglage, while the link chronograph mechanism shows black-polished steel components.

There are two additional details of note. First, the dial does not have the signature of Svend Andersen or his brand Andersen Geneve, but instead, "Henry link Birks" on the outer circumference link of the dial at six o'clock. Henry Birks is a link luxury jeweler founded in Montreal, Canada.
