The dual scale on the bezel is noted as surprisingly useful, and the crown action, winding, and hacking are reported to work perfectly.

On balance, owners rate the Serica Ref. 5303 Diving Chronometer highly for its blend of unique design and robust functionality.

Horage Lensman 2

The Horage Lensman 2 is recognized for its innovative photographic exposure calculator bezel and legible dial, making it a functional tool for outdoor photography. Reviewers highlight its well-executed 39mm hybrid titanium and aluminum case, COSC-certified K2 GMT movement, and overall good sizing. The watch is priced at CHF 5,450. On balance, reviewers rate the Horage Lensman 2 highly for its unique functionality as a camera tool combined with its luxury micro-rotor GMT features.

From video reviewers

The K2 Micro-Rotor Calibre is a key innovation in the watch. The watch's prominent lug-to-lug fit may be noticeable compared to other watches. Reviewers disagree on the importance of the sliding exposure scale on the bi-directional bezel, with some considering it a unique feature for photographers and others not explicitly mentioning it as a notable aspect.
