What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Horage Omnium K2

The Horage Omnium K2 is lauded for its slim 7.95mm profile and chronometer-certified K2 micro-rotor movement with a 72-hour power reserve. Reviewers note its technical innovation, including a proprietary silicon escapement and modular K1 movement, and praise its value. However, some find the molded, luminous hour numerals too whimsical, and the explicit mention of "silicon escapement" on the dial is considered unnecessary. On balance, reviewers rate the Horage Omnium K2 highly for its technical innovation and slim profile at its price point.

Praesidus A-5 UDT

The Praesidus A-5 UDT is noted for its historically inspired design, featuring an oversized crown cap and chain that pays homage to WW2 canteen watches. Reviewers highlight its functional dial with embossed, Super-LumiNova filled numerals and markers for legibility, alongside 200m water resistance and a 38mm brushed stainless steel case. Some owners find the 11.7mm thickness problematic, describing it as disproportionately tall. The watch's ana/digi functionality and connection to special operations forces are also praised. On balance, owners and reviewers appreciate the Praesidus A-5 UDT for its unique historical design elements and functional dial.
