What people say

Owners + reviewers, side by side

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

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.

Zelos Aurora Field

The Zelos Aurora Field is praised for its unique and gorgeous dial, with the hammered teal bronze version and its great lume, particularly on the minute track, being singled out. Owners find the rubber strap comfortable and flexible with good hardware, and the watch is highlighted as feature-packed for its price point, including 200m water resistance, Grade 2 titanium, and 30,000 A/m anti-magnetism, with the new clasp noted as the best to date. However, some owners criticize sharp bracelet edges, an odd case shape with lugs that cause it to wear high, and dial text that appears cheap and plasticky, with one commenter finding the straight lugs look a bit off. Overall, owners rate the Zelos Aurora Field highly for its value and unique dial, despite some concerns about case and bracelet finishing.
