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.

Echo/Neutra Rivanera Piccolo

The Echo/Neutra Rivanera Piccolo is praised for its charming and impressive design, featuring a lightweight 26mm grade 5 titanium case with a sandblasted finish and polished edges. It is powered by an automatic Sellita SW1000 elaboré grade movement with a 46-hour power reserve and is available with an ultra-black Musou Black dial option. One reviewer suggested removing the date for a cleaner dial, while both sources note the straps lack a quick-release system. Overall, reviewers highlight the Rivanera Piccolo's distinctive design and titanium construction as its primary strengths.

From video reviewers

The thin 6.9mm case is a standout feature. Reviewers noted the Grade 5 titanium case construction. No shared weaknesses were identified.
