Angular, then softened.
A rounded-octagonal middle case creates the structure. The slim circular bezel inside it keeps the dial approachable and recognizably Four77.
Integrated automatic sports watch
COAST
A flowing steel sports watch shaped by the meeting of water and sky. Angular case facets transition directly into the bracelet while a polished round bezel and wave-relief dial keep the design unmistakably coastal.

Steel in motion
The bracelet begins at the case.
COAST treats the case and bracelet as one continuous object. Broad brushed surfaces carry through the first links, interrupted by narrow polished edges that move with the wrist.
A controlled taper.
Articulated links narrow quickly from the case, balancing the broad facets with a bracelet designed to wear compactly.
A signature at six.
Horizontal relief runs across the dial while the polished wave at six becomes both an hour marker and the watch’s signature.
Working specification
A modern sports watch within reach.
A no-date automatic movement, moderate dimensions, and straightforward three-hand architecture keep the concept focused on case finishing and bracelet integration.

One form, from foam to final light.
Harbor establishes the deep-blue identity, Foam reverses the contrast, Kelp brings restrained gilt warmth, Ember turns the dial into smoked copper, and Last Light captures the fleeting orange-to-blue horizon of a Pacific Northwest sunset.
