Praesidus A-5 UDTvsSeiko Prospex Sea

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.

Owners widely praise the Seiko Prospex Sea for its excellent lume, robust build, and value, with many highlighting the comfortable 4 o'clock crown and reliable movements. Reviewers note impressive case finishing and attractive dials, with specific models lauded for their gradient blue designs and smooth bezel actions. Accuracy figures vary, with one owner reporting +9 seconds/day after demagnetization, while others find the watches to be good first "proper" watches. Some owners find the stock rubber straps uncomfortable or the overall size substantial on smaller wrists. On balance, owners and reviewers rate the Seiko Prospex Sea highly for its combination of strong dive watch functionality and appealing design at its price point.
