What people say

Owners + reviewers, side by side

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

CWC T20 General Service Quartz Watch

The CWC T20 General Service Quartz Watch is widely praised for its simple, clean, and classic look, with owners considering it a classy and comfortable field watch. Its 38mm tonneau case is seen by some as a cool retro piece representative of original MOD specifications, though others find this size too small for larger wrists. The watch is noted for keeping accurate time, with one owner reporting it as practical for everyday wear. It features a stainless steel case, sapphire crystal, and a Ronda 715 movement. A limitation mentioned is the fixed lugs, which restrict strap versatility. Overall, owners rate the CWC T20 General Service Quartz Watch highly for its classic military-inspired aesthetic and reliable timekeeping at an affordable price.

LONGINES AVIGATION BIGEYE

Owners and reviewers widely praise the Longines Avigation Bigeye for its unique, asymmetric dial, vintage military aesthetic, and cohesive design, with one reviewer noting its GPHG Best Revival prize win. The tactile chronograph pusher action and reliable L688.2 column wheel movement are highlighted, as is the watch's legibility and versatile strap-swapping potential due to its 20mm lug width. However, criticisms include the 30-minute sub-dial's three-minute hash marks, which some find compromise reading speed, and the lack of drilled lugs. The watch's thickness, around 14.45mm, is noted as typical for its movement, and some owners mention minor QC issues with chronograph hand alignment and a loud rotor. On balance, owners and reviewers rate the Longines Avigation Bigeye highly for its distinctive vintage-inspired design and solid chronograph performance at its price point.
