Blancpain Fifty Fathoms Automatique 38mm

Blancpain expands its flagship dive watch collection with the debut of the Fifty Fathoms Automatique 38mm, marking the first time this core model is offered in a reduced case size. Previously, only the Bathyscaphe line featured 38mm variants, making this a notable evolution for the brand’s most iconic diver. The launch arrives in two distinct editions, one in grade 23 titanium with a pink dégradé dial, the other in 18k red gold with a smoky black dial, both powered by the high-performance calibre 1153 and aimed at collectors seeking a more wearable take on the classic Fifty Fathoms.
The new Blancpain Fifty Fathoms Automatique is housed in a compact case measuring 38.2mm in diameter and 12mm in thickness, with a lug width of 19mm that tapers to 18mm at the strap. It is available in two material options: luxurious 18k red gold or ultralight grade 23 titanium, an unusually high-spec alloy in the watch industry, more commonly used in aerospace or medical fields than in horology. The finishing is clean and tool-like, with brushed surfaces that highlight the functional nature of this downsized diver.Around the back, the watch features a sapphire exhibition caseback that reveals the in-house Blancpain calibre 1153. The movement is elegantly finished and fitted with a skeletonized rotor that adds visual depth while keeping the overall aesthetic refined and modern.A screw-down crown and unidirectional rotating bezel provide solid tactile feedback and reinforce the watch’s functional identity. All topped by a cambered sapphire crystal that safeguards the front of the watch, offering distortion-free legibility. Water-resistance can reach up to 300 meters (1,000 feet).
Time is displayed on a clean mother-of-pearl dial with no date window, allowing for a symmetrical and elegant design. Applied gold hour markers give it a crisp, polished look, framed by a subtle chapter ring that adds visual balance without clutter. The surface shifts in tone depending on the light, lending softness and nuance to the overall aesthetic.Two colorways are offered. The titanium version features a light pink dégradé dial that fades to a deeper rose tone at the edges, paired with matching white gold accents. The red gold model introduces a smoky black gradient, transitioning from silvery gray at the center to a near-black periphery, darker, more dramatic, and well-suited to its warmer case tone.
The sword-style hour and minute hands, along with a lollipop seconds hand, are crafted in gold to match the case. Super-LumiNova is applied to all hands and markers for low-light legibility, keeping the design functional without interrupting its refined character. The gold-tone elements stand out crisply against the gradient mother-of-pearl, ensuring clarity even on a dial designed for elegance.

The “Blancpain Fifty Fathoms Automatique” (References below) is powered by the in-house automatic mechanical movement, calibre 1153 with 28 jewels, 186 components, and a frequency of 21,600 vibrations per hour (3 Hz). It is equipped with a stop-seconds mechanism and a skeletonized rotor visible through the sapphire exhibition caseback. Power reserve can last up to 100 hours, when fully wound.
Mounted on the watch is either a NATO strap, a sail-canvas strap, a Tropic-style rubber strap, or a grade 23 titanium bracelet, each offering a distinct look and feel. The titanium bracelet provides a more integrated, modern aesthetic, while the rubber and canvas options lean into the sporty, functional character of a dive watch. All variants are secured by either a pin buckle or folding clasp, depending on the configuration.
