The new Bremont Supermarine S300 White shares a lot of technical similarities with its S300 predecessors. The dimensions remain the same at 40 mm x 13 mm, as does the BE-92AE chronometer-grade caliber with a 38-hour power reserve. The stainless-steel case features Bremont’s proprietary Trip-Tick construction. Water resistance is specced to 300 meters thanks, in part, to the screw-in caseback that features an engraving of the Supermarine Spitfire aircraft in relief, a nod to Bremont’s focus on aviation history. The sapphire crystal is domed and has gone through an anti-reflective treatment. There’s a color-matching date aperture at 3 o’clock. The numerals and indexes are coated in Super-LumiNova, as are the nickel-satin hands.
What makes the Supermarine S300 White different than previous iterations is primarily due to its painted white dial color that is complemented by a dark blue ceramic bezel. Following the Supermarine Waterman unveiled last summer in the S500 series, this is the first light-colored dial seen inside the S300 series. While dive watches with white dials aren’t necessarily uncommon, they are far less popular than black, gray, or blue dials. Offering up a lighter-toned option makes sense and serves as a nice contrast to the rest of the S300 series. Matching the overall wearability of the S300 line, the new colorway should appeal to those interested in dive watches as daily wearers compared to those looking at them as a professional investment. The Bremont Supermarine S300 White is priced in line with previous S300 entries at $4,095 and comes on a blue Temple Island rubber strap and an additional blue and white striped NATO strap (lug-to-lug is 20 mm).
While I’ve discussed the new model’s appeal to the desk divers among us (myself included), I would be remiss to not mention the fact that Bremont ambassador and acclaimed adventurer Nirmal ‘Nims’ Purja MBE has announced that the S300 White will be accompanying him during his upcoming “Project Possible 14/7” mission. This record-breaking journey involves climbing the world’s 14 highest peaks — all standing over 8,000 meters tall — in only seven months. Purja will begin his attempt starting this March.
