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 Hammerhead 43 Field

The Zelos Hammerhead 43 Field is praised for its unique bronze case patina potential, masculine angular design, and fantastic lume. Owners also highlight the lovely Mosaic Ember and purple agate dials. However, some owners feel the 43mm case wears large, suited for wrists 7.5 inches and up, and a reviewer notes its substantial 17mm thickness. The rubber strap is disliked for making the watch feel top-heavy, and the date window is considered tiny and hard to see. Some owners express disappointment with the NH movement. Overall, owners and reviewers rate the Zelos Hammerhead 43 Field well for its distinctive design and dial appeal at its price point.
