What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
