What people say

Owners + reviewers, side by side

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

MKII Hellion

The MKII Hellion is widely praised for its immaculate fit and finish, with a mirror-polished case that bridges field and dress styles. Owners appreciate its vintage-inspired lug design and the satisfying heft that balances classic appeal. The large crown is a noted feature, adding a masculine touch to the refined design. One owner questions if the price aligns with the specifications. Overall, owners rate the MKII Hellion highly for its exceptional finishing and versatile, refined design at the 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.
