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.

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.
