Bremont Supermarine All-Ceramic “Deep Blue”
An Underwater World
In 2024, Bremont introduced the Supermarine All-Ceramic collection, incorporating full-ceramic construction into its 500-meter-rated dive watches. The latest addition, the “Deep Blue”—limited to 250 pieces—features a matte blue ceramic case and dial, the latter adorned with a 3D wave pattern. The 43mm ceramic case houses a titanium inner chassis and is fitted with a titanium case back. Powering the watch is the automatic caliber BB64AH, which offers a 56-hour power reserve. The Deep Blue is available with a choice of three distinct strap styles. As someone who is a great fan of ceramic as a case material and has a particular fondness for high-performance deep-dive watches, I have naturally become a great admirer of this timepiece.
The Bremont Supermarine All-Ceramic “Deep Blue” is a special edition within the brand’s 43mm ceramic dive watch line. Building upon the Supermarine All-Ceramic collection launched in 2024, this model introduces a blue ceramic case and bezel. Its color palette is inspired by the meeting point of the ocean and glaciers, with a black, wave-patterned dial that provides a striking contrast against the hands and hour markers.
The watch utilizes an integrated ceramic case design with a titanium inner chassis—rather than having every structural component made of ceramic. A titanium unidirectional rotating bezel supports the ceramic insert, while a screw-down titanium case back ensures the integrity of the seal. Rated for water resistance up to 500 meters and equipped with a helium escape valve, the watch is powered by Bremont’s proprietary automatic caliber BB64AH, featuring time and date functions. Bremont ambassador and former Royal Marine Commando Aldo Kane wore this “Deep Blue” model during an expedition in Iceland, which included diving in glacial lakes and traversing glaciers. Previously, Kane had also worn the “Jungle Green” and “Tactical Black” versions of the all-ceramic collection while conducting scientific research in jungle environments. This trip to Iceland served as a testing ground in frigid waters for this timepiece, which centers on a design featuring blue ceramic, a textured dial, and an all-ceramic aesthetic. online copy watches
Case and Dial
The integrated case is crafted from deep-blue ceramic with a matte, sandblasted finish. Bremont produces these ceramic components by sintering ceramic powder at a high temperature of 1,450°C—a process during which the case shrinks by 23%. While the ceramic offers exceptional scratch resistance, the watch employs a multi-material construction, incorporating an internal titanium housing and a PVD-treated titanium case back. Consequently, despite being part of the “all-ceramic” collection, the case is not composed entirely of ceramic.
The watch measures 43 mm in diameter, with a lug-to-lug length of 50 mm and a thickness of 13 mm. The 50 mm lug-to-lug dimension provides a more accurate sense of how the watch wears than the diameter alone, while the 22 mm lug width accommodates a suitably substantial strap. The watch head weighs 74 grams (excluding the strap)—a detail worth noting when comparing the three available strap configurations. A screw-down crown, a helium escape valve, and a water-resistance rating of 50 bar (50 atmospheres) round out the watch’s professional-grade diving specifications.
The rotating bezel consists of a knurled titanium outer ring fitted with a blue ceramic insert, which features large numerals, rectangular indices, and an orientation marker at the 12 o’clock position. It is a unidirectional bezel, allowing the diver to align the elapsed-time scale with the minute hand; it cannot be rotated in the opposite direction, ensuring that the indicated remaining time cannot be inadvertently extended. The dial is protected by a domed, anti-reflective sapphire crystal. On the reverse, a blue PVD-treated titanium screw-down case back features an engraving of a world map centered on the oceans, rendered in a Spilhaus projection. replica watches for sale
Horizontal wave patterns across the dial create a rich sense of depth, all without the need for additional sub-dials or alterations to the central hand configuration. The applied hour markers feature an alternating design of circles and elongated trapezoids; the latter align with the larger markers on the bezel, creating a crosshair-like configuration. The outer perimeter of the black dial displays a minute track, accented with orange dots at the quarter-hour positions. At 3 o’clock, the date window houses a matching black date disc, which minimizes the visual contrast between the calendar display and the dial.
The hour, minute, and second hands are centrally mounted and crafted from polished, black-gold-plated material. Both the hands and the hour markers are coated with white Super-LumiNova that emits a blue glow, ensuring clear legibility even in low-light conditions. The central second hand features a striking arrow-shaped tip, while the broad hour and minute hands are filled with a high-contrast luminous coating. Above the 6 o’clock position, the word “Supermarine” appears in orange, echoing the small orange markings found along the minute track.
Movement
The BB64AH is a self-winding mechanical movement featuring central hours, minutes, and seconds, with a date display positioned at 3 o’clock. It operates at a frequency of 28,800 vibrations per hour (4 Hz) and contains 25 jewels. The movement is equipped with a Glucydur balance wheel, an Anachron hairspring, and a Nivaflex mainspring. The traditional central time display allows the entire dial surface to be dedicated to a wave-pattern relief and relatively large, luminous hour markers. perfect fake watches
When fully wound, the movement offers a 56-hour power reserve—enough to run for two days, with 8 hours to spare. The movement is housed within a titanium inner case and protected by a solid titanium case back; consequently, the engraving on the case back takes precedence over any view of the movement itself. The self-winding system and date display serve as essential everyday functions, while the rotating dive bezel operates independently of the movement.
Strap
One configuration pairs a deep blue dial with a blue rubber strap, featuring an embossed texture on the surface and a leather lining. White stitching along the upper edges of the strap provides a striking contrast against the blue-and-black color scheme of the case and dial. This strap utilizes a quick-release system, allowing for easy removal without the need for traditional spring-bar tools. The strap width is 22 mm.
Two other strap options offer different aesthetics and constructions while keeping the watch head unchanged: a black-and-blue woven NATO-style strap, which creates a layered, continuous look, and a black rubber strap featuring a raised V-shaped pattern—also equipped with a quick-release system. The woven strap incorporates a blue stripe across the black fabric, while the V-pattern rubber strap maintains the blue-and-black palette of the case. Please note that these are individual strap options, not a set containing all three.
The Bremont Supermarine All-Ceramic Deep Blue watch is available with a choice of three straps: an embossed blue rubber strap (with leather lining), a black-and-blue woven NATO-style strap, and a black rubber strap with a V-shaped (chevron) pattern. Buyers can choose from a variety of strap materials and aesthetic styles, all while retaining the signature blue ceramic case, wave-patterned dial, and the BB64AH movement. This timepiece is a limited edition. wholesale watches replica
Following the “Jungle Green” and “Tactical Black” versions, this deep blue model is the latest addition to Bremont’s all-ceramic Supermarine collection for 2024. Its limited production run and distinctive colorway set it apart within the collection, while the 43mm case size and 500-meter water resistance remain central to its design.
