Previous non-"Excellence" models had the Caliber 100-03 and 100-04. This will likely be phased out very soon, and I fully expect Glashütte Original replica watches to keep putting the caliber 36 in more movements. One of the nice things that I think people will appreciate is that now the big date and moon phase indication complications are each set with the crown, as the inset case pushers have been eliminated. A big thumbs up for that, as it makes adjusting the watch more convenient and the case overall more aesthetically pleasing. The moon phase complication now lasts for about 122 years before having to adjust it. But I am sure the movement will need a few services during that time... You also have a more precise jumping date complication rather than a slightly slower-moving one when midnight hits rolex replica. I also want to mention that adjusting the big date complication is more satisfying from a tactile perspective. You get a nice solid sounding "clink" when you change the date which I think you'll really enjoy. Overall, these aren't just the same Senator Panorama Date and Panorama Date Moon Phase watches with a new movement, but rather tweaks and enhancements that you can feel and appreciate. I spend a lot more time talking about the Caliber 36 in an upcoming, more full review. Suffice it to say that this is an excellent base caliber operating at 4Hz with 100 hours of power reserve, a silicon balance spring, and fantastic performance that comes complete with a omega replica watches certification from the brand with individualized performance results. The 40mm-wide case size is also unchanged, and the Glashütte Original Senator Excellence Panorama Date and Moon Phase watches continue to look handsome yet substantial on the wrist. Thicker than the time-only, three-hand Senator Excellence, it feels like a solid 40mm rather than something smallish. I will, however, say that if you are the type of person who feels 40mm is a large watch and that 42mm wide is too large, I recommend that you make sure to get a shorter strap for the watch or opt out of the folding deployant buckle, as it will not be as comfortable as the breitling replica with a more traditional ardillon-style pin buckle on the glossy black alligator strap.
