Bremont has made a statement with its revamped Supermarine 300m. For those following the brand’s rebranding efforts, this model highlights their shift towards a cleaner, more refined aesthetic while maintaining the rugged functionality they’re known for. The new green dial version of the Supermarine 300m showcases how the brand is evolving, but in a way that still feels grounded in its adventurous heritage. The Supermarine makes a strong case for one of the best, but most overlooked luxury divers on the market today.
On-Wrist: Bremont Supermarine Green Dial Review
One of the key updates is the redesigned 40mm case, crafted in 904L stainless steel, which is known for its enhanced durability and corrosion resistance. This sleeker profile offers a more comfortable fit on the wrist while retaining the toughness you’d expect from Bremont. The symmetrical design now includes both crown and bezel guards, which add an extra layer of protection, ensuring smooth operation without the risk of accidental adjustments or damage. The crown is easy to manipulate even with gloves on, and tucks away nicely under the guards.
The anodized green aluminum bezel features trapezoid-shaped markers that flow onto the dial, creating a naval-inspired crosshair effect. It’s a detail that adds character without feeling overdone, showing off Bremont’s knack for balancing modern design with functional elements.
The real showstopper here is the green gradient dial, which shifts from deep forest green at the edges to a lighter, sunburst hue at the center. This color play creates a sense of depth and movement, making the dial visually engaging in different lighting conditions. In certain conditions, the dial looks completely black, which is welcomed under low light.
The polished nickel-plated hands and applied indexes are filled with Super-LumiNova®, which glows a sharp blue in low-light settings, ensuring legibility at all times. The anti-reflective, domed sapphire crystal offers excellent clarity, while also being scratch-resistant—another nod to Bremont’s focus on durability. The applied and bordered numbers at 3, 6, and 9 catch light along with the hands in an attractive manner. They shine without being too much.
Bremont has also introduced a new 904L steel bracelet for this model, and the attention to detail is clear. The alternating polished and satin-finished links form a fluid, comfortable fit that adapts well to any wrist. It’s an upgrade that adds both style and practicality, making the watch easy to wear throughout the day. For those who prefer a different look, the Supermarine 300m is also available with a military-inspired rubber strap or a vintage brown leather strap. These options give the watch an added layer of versatility, allowing it to shift between casual and more formal settings with ease.
Under the hood, the watch is powered by Bremont’s modified Calibre BE-92AO automatic movement. With 25 jewels, a Glucydur balance wheel, Anachron balance spring, and a 50-hour power reserve, it’s designed for reliable performance, whether you wear it daily or take it on occasional dives. The movement beats at 28,800 vibrations per hour (4Hz), ensuring smooth operation and accuracy.
The case measures 40mm in diameter and 12mm thick, giving it a balanced presence on the wrist. Rated to 300 meters of water resistance, the Supermarine 300m is more than capable of handling any underwater adventures. The unidirectional rotating bezel and screw-in crown add further reassurance for those planning to put the watch through its paces.
The Supermarine 300m represents where Bremont is heading as a brand. With its rebranding effort in full swing, Bremont is refining its designs, focusing on slimmer, more elegant profiles without sacrificing the durability that’s been at the core of their identity. The engraved case back featuring a world map reinforces the spirit of exploration that Bremont continues to embody.
The Bremont Supermarine 300m Green Dial strikes the right balance between a functional tool watch and a refined everyday timepiece. With its striking green gradient dial, improved case design, and versatile bracelet options, it offers something for both long-time fans of the brand and those discovering Bremont for the first time. This is a solid addition to the collection, reflecting the brand’s evolution while staying true to its roots.
Priced at $3,650, it’s certainly an investment, but one that feels justified given the level of detail, performance, and versatility on offer. If you’re looking for a dive watch that can transition seamlessly from the ocean to a dinner date, the Bremont Supermarine 300m is a top contender.
