Description

Australian collectors usually want two answers before committing: how it wears, and what happens if something goes wrong. This page covers both — specifications first, then how our Australian warranty and returns work.

Seamaster 300 – an updated icon
Symmetrical 41mm case and bracelet in stainless steel

Blue bezel with a summer blue diving scale

AN UPDATED 1950s ICON

First created in 1957, the Seamaster 300 is one of the most famous watches in underwater history.

The updated models embrace a new, vintage-inspired design that embraces the past whilst also offering the very best in modern accuracy.

While staying true to the heritage look, the new design provides a slenderer aesthetic, thanks to domed sapphire glass, alongside a thinner bezel built from an oxalic, anodized-treated aluminium.

SUMMER BLUE

The sleek Summer Blue dial features rhodium-plated hands, recessed hour markers, and open numerals, all filled with a unique light blue Super-LumiNova for incredible visibility.

Mirroring the tones of the dial, the blue ceramic bezel comes with a summer blue enamel diving scale, while on the reverse, the case back comes with a stamped, commemorative Seamaster logo.

The 41mm stainless steel case fastens securely with a steel bracelet. Powered by a Co-Axial Master Chronometer calibre 8912 movement, this watch is also water resistant to 300 metres.

BEFORE YOU ORDER FROM AUSTRALIA

Two things are worth checking on a piece like this: the case diameter against the wrist you are buying for, and whether the bracelet or strap can be sized without a specialist. Both are listed above. If you are comparing references, note that Australian pricing already reflects landed cost, so the figure you see is the figure you pay.

Buying from Australia — all prices are shown in AUD. Delivery is domestic and returns are handled by our Australian team, so you are not posting a watch back overseas if the fit is not right. If you want to compare before deciding, our collection pages group every model by brand.
