First off, this watch is gorgeous and I love it.
The picture and description are a bit misleading, as I'd hoped, and the face isn't as large as it looks and sounds (42 mm, or just under 2 inches.)
For a watch strap, the leather is surprisingly thick and inflexible. It took a month to get to the point where it isn't a hassle buckling or unbuckling it.
Also, it's a chronometer, so the second hand is one of the three smaller faces, and the full-size second hand is the stopwatch hand, which is a bit confusing at first.
The really big problem though is with the instructions. Jack Mason is paperless, and includes a URL to access the instructions online. But, the URL is a broken link and doesn't even reach the brand's website, or any website at all. I had to google the brand name to find the website, then go back and google instructions for the watch, because navigating the poorly-designed website is nearly impossible.
You wouldn't think instructions would be so big an issue with a watch, but the adjustment dial is far from intuitive. The watch deserves a 5-star rating, because this is a watch people should have, but the Jack Mason brand deserves nothing better than a 3.
