On the wrist

The Seaforth Bronze takes the familiar compact Seaforth template and changes its mood completely. At 40mm across, 48mm lug-to-lug, and about 12mm thick, it keeps the wearable proportions that helped make the line popular, but the aluminum-nickel bronze case gives the watch a warmer, more personal character as it ages. The fixed bezel makes it read less like a pure timing instrument and more like a rugged everyday sport watch.\n\nThe blue and green sunburst dials associated with the bronze run pair naturally with the gold-brown case tone, while Super-LumiNova and 200m water resistance preserve the functional diver base. The stainless steel caseback is a practical touch because it keeps bronze off the wrist, and the ETA 2824-2 gives the watch a familiar, easily serviced Swiss automatic heart.

Bottom line

A compact, character-rich bronze Seaforth that pairs proven dive-watch specs with patina-friendly material and cleaner fixed-bezel styling.

Who it's for

Collectors who want the Seaforth proportions in a warmer bronze case, prefer a clean fixed-bezel look, and are comfortable buying a discontinued Halios model on the secondary market.

Who should skip it

Skip it if you dislike bronze patina, need a rotating elapsed-time bezel, or want current retail availability; this is a discontinued collector-market Seaforth variant.

Before you buy

Bronze will darken and patinate with wear
Fixed bezel gives less dive-timing utility than rotating Seaforth variants
Discontinued model; verify condition, caseback, and included straps when buying pre-owned
Secondary-market pricing can sit above original retail due to Halios demand

FAQ

Is the Seaforth Bronze automatic or quartz?

The Seaforth Bronze is automatic. The ETA 2824-2 winds itself from the motion of your wrist, so it needs no battery. A full wind holds roughly 38 hours, so it keeps running overnight off the wrist; left longer it stops and restarts once you wear or hand-wind it.

What movement does the Seaforth Bronze use?

The Seaforth Bronze is powered by the ETA 2824-2 from ETA, an automatic caliber with 25 jewels, a 38-hour power reserve, and a 28,800 bph beat rate. Being automatic, it winds from the motion of your wrist and needs no battery.

How water resistant is the Seaforth Bronze?

The Seaforth Bronze is rated to 200 m. That is true dive territory: fine for swimming, snorkelling and recreational scuba diving, as well as all daily wear. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.

How big does the Seaforth Bronze wear?

At 40 mm across with a 48 mm lug-to-lug and 12 mm thick, the Seaforth Bronze wears as a modern medium-to-large watch. Lug-to-lug is the measurement that really decides fit, since it sets how far the case spans the wrist — 48 mm suits most wrists, and smaller wrists especially should check that figure.

What material is the Seaforth Bronze case?

The Seaforth Bronze uses an aluminum-nickel bronze case with a stainless steel caseback. Like other bronze watches, it will darken and develop patina over time.

Is the Seaforth Bronze a real dive watch?

Yes. Even with its fixed bezel, the Seaforth Bronze is rated to 20 ATM / 200m and uses a screw-down crown, making it suitable for swimming and recreational dive use when properly serviced.
