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.

Spinnaker Croft 39 GMT

Owners praise the Spinnaker Croft 39 GMT for its colorful design, NH34 GMT movement, and reasonable price, noting high-standard manufacturing on the case, bezel, and bracelet. One owner finds the 43mm case and 51mm lug-to-lug dimensions too large for the design, preferring a 39-40mm case size. A potential issue with the lume was noted by one user. On balance, owners value the Spinnaker Croft 39 GMT for its attractive design and build quality at its price point, though sizing is a point of contention for some.
