Seamaster 300M (42mm, Blue Dial)
The James Bond Seamaster. Blue wave dial, helium escape valve, ceramic bezel (post-2018). Most recognized Omega model in Thailand. Strong pre-owned demand.
Seamaster Planet Ocean 600M (43.5mm)
The deeper-dive Seamaster. Co-Axial escapement, Master Chronometer. Larger case appeals to buyers who find 300M too subtle. Better water resistance.
Seamaster Aqua Terra (41mm, Green)
The dressy Seamaster. Teak-pattern dial, no crown guards. Golf-edition green dial (Daniel Craig era) is particularly liquid. Office-appropriate size.
Seamaster 300 Heritage (41mm)
The 1957 reissue. Broad arrow hands, vintage lume. Appreciated collectors model — less common than 300M so slightly harder to resell, but gaining value.
