What people say

Owners + reviewers, side by side

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

Formex Essence ThirtyNine

The Formex Essence ThirtyNine is praised for its impressive build quality and value, featuring a patented case suspension system for comfort and protection. It houses a COSC-certified Sellita SW200-1 movement with a 38-hour power reserve and a tool-free strap quick-release system. A minor inconvenience noted is the specific closing order of the clasp. On balance, reviewers rate the Formex Essence ThirtyNine highly for its comfortable wearability and excellent value 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.
