Which ref to buy

The Supermarine is Bremont's dive watch, rated to 300m. Uses the TRIP-TICK case construction common to the Bremont tool watch lineup. Named after the Supermarine Spitfire aircraft, consistent with Bremont's aviation/British heritage branding.

Bremont Supermarine S301 · S301-BKConsider
Supermarine S301 -- Bremont's diver, 300m rated, TRIP-TICK case, strong British tool watch identity.
The case for it:
The TRIP-TICK three-part case construction is a genuine engineering feature: hardened steel barrel, softer steel top and bottom ring for impact absorption. The Supermarine applies this to a legitimate 300m diver.
Consider instead if:
Bremont's secondary market is weaker than comparable Swiss divers. The TRIP-TICK case is genuinely interesting but the Supermarine competes against Tudor Pelagos and Oris ProDiver at a price premium that requires confidence in the brand.
