Jaeger LeCoultre Master Ultra Thin Moon
Number of jewels: 42
Sinn uses an all high-polished steel case that is 41mm wide. It looks great matched with the black rotating diver's style bezel. The chronograph pusher are simple plunger style to add to the vintage feel. Over the dial is a domed acrylic crystal - typical of older sport watches. The case is water resistant to 200 meters. Sinn likes to point out that the dial is done in a matte black tone. You'll notice a picture of white with the "aged" yellow look of the hour markers and lume on the hands. Sinn designers did a good job of creating that iconic spiral scale on the dial, but also not making the dial look too busy. Part of this has to do with the diminutive gray colored subsidiary seconds dial, and well-integrated date window. I really don't think anyone is going to use the tachymeter function, but it looks cool enough.

On the wrist, the ALT1-WT's 43mm width and 139g weight (with leather strap and deployment) is quite manageable and I think the World Timer wears a little slimmer than its 16mm height would suggest. The dial is a flat black and exhibits a subtle but effective globe design which is carried over from the aforementioned C-17 Globemaster. While I was at first skeptical of the design, in person it adds depth and character to the World Timer and sets the ALT1-WT apart from the other chronographs in the Bremont family. This is not a cheap watch and it is these sorts of details, from the hardened case to the detailed design and fine finishing which set the Bremont apart from a less expensive watch or even many of the watches available at a similar price point.
