Inside the bunker-like case is the new Omega Co-Axial Master Chronometer Caliber 8912 movement. Co-Axial you should already be familiar with - it's Omega's proprietary escapement design (originally invented by George Daniels and painstakingly industrialized in the late 1990s and early 2000s by Omega and ETA engineers) that promises lubrication-free operation and consequently longer service times. Master Chronometer is a new development from Omega and refers to its continuously extensive line of timepieces that have undergone internal tests certified by METAS.

Basically, in December 2014, Omega announced that it was working with the Swiss Federal Institute of Metrology, METAS, to have it independently certify Omega's internal tests and that they would also submit their movements designated by the Co-Axial Master Chronometer. No, the Swiss replica watches are not certified by METAS, but the 10-day test procedures check fully enclosed watches for timekeeping during and after exposure to 15,000 Gaussian magnetic fields and in six positions and at two different temperatures and at 100% and 33% power reserve. Finally, they also test the waterproofness of the cases, complete replica watches.

The in-house made and METAS certified tested Omega Co-Axial Master Chronometer 8912 in the Ploprof, new for 2016, is largely based on the Co-Axial 8500 that preceded it. It has two spring barrels connected in series (this time in discreet and cool black housings), with the typical and beautiful replica Omega swirling Geneva stripes and laser-sharp red lettering on both the movement plates and the automatic rotor. The power reserve is a generous 60 hours.

The caseback features a very thick piece of sapphire - leaving absolutely no excuse for brands that, for some weird reason, prefer solid casebacks on watches with a depth of a few hundred meters. I already mentioned the rather refined finish, but I also have to emphasize the cumulative effect of the almost matte case and the shiny and beautiful movement: there is a certain wow factor that is emitted by the inner beauty of the Ploprof.

Finer details of the Caliber 8912 that I could appreciate include its extremely quiet operation - although I assume the 1,200-meter-depth casing dampens quite a bit - and the complete absence of annoying vibrations from the automatic rotor that lead to today in a lot of ETA and some pretty high-end internal moves. Omega has removed the date from the 4:30 position where it used to be on steel Ploprof watches, while still retaining the quick-hour jump adjustment function. This ensures that, after unscrewing and pulling the crown to the first position, the hour hand can move forward or backward in 1-hour increments - very useful when traveling as the minute and second hands keep running so you can adjust for a new time zone without wasting the correct time you already had.
