Blancpain Bathyscaphe 70th Anniversary Brings the 1968 Skin Diver Back at 37.4mm
A hands-on look at the new Blancpain Fifty Fathoms Bathyscaphe 70th Anniversary, a 300-piece limited edition that revives the compact 1968 skin diver with modern ceramics and the 100-hour Calibre 1150.

Blancpain has a habit of marking diving anniversaries properly, and the latest one lands with unusual precision. The Fifty Fathoms Bathyscaphe 70th Anniversary, shown to press this week ahead of its boutique rollout, is a 300-piece limited edition that reaches back to 1968 for its blueprint and comes back with almost nothing lost in translation. After seventy years, the civilian side of the Fifty Fathoms family finally gets the tribute it deserves.
I spent most of the briefing with the reference on a tray rather than behind glass, which turned out to be the right way to understand it. The first thing you notice is how small it feels in an era of oversized divers. The polished steel case measures 37.4mm across and 12.3mm thick, with a lug-to-lug span of 46.5mm. Those numbers mirror the 1968 original almost exactly, and Blancpain representatives were upfront about the effort involved. The case was engineered around the modern movement specifically to preserve those compact proportions, because a faithful reissue with a thick mid-case would have defeated the purpose.
The design brief was clearly fidelity over reinvention. A steel bezel carries a black ceramic insert with lacquered numerals, standing in for the hesalite unit fitted in the sixties while offering far better scratch resistance. It rotates through 120 clicks with a smooth, damped action that immediately felt more refined than most dive bezels I have handled this year. The knurled screw-down crown sits flush against the case flank without crown guards, keeping the silhouette clean.
Under a domed sapphire crystal sits the dial that anchors the whole concept. The sunburst meteor-grey surface shifts between charcoal and silver depending on the light, and the mid-century Blancpain logo with its elongated roman lettering sets the vintage tone before you even register the details. Baton hands and 18K white gold baton indexes carry vintage-toned Super-LumiNova, which glows warm rather than bright and photographs beautifully against the grey backdrop. An arrow-tipped seconds hand adds a subtle asymmetry, and a discreet date window tucks in at 3 o’clock without disturbing the symmetry. The finishing touch is the hand-stitched chocolate calf leather strap on 18mm lugs, closed by a pin buckle. It arrives stiff from the box but softens quickly, and the brown-on-grey combination gives the watch a distinctly civilian character.
Flip it over and the anniversary story becomes mechanical. Where the 1968 watch hid its movement behind solid steel, this edition opens up with a sapphire caseback revealing Calibre 1150, the manufacture automatic that also powers the current 38mm Fifty Fathoms Automatique. It runs at 21,600 vibrations per hour, holds 28 jewels across 210 components, and delivers a generous 100-hour power reserve thanks to twin barrels. The silicon hairspring brings meaningful resistance to magnetism, something the original wearer could never have imagined. Finishing is where Blancpain earns its price tag. The plates show rifled soleil snailing, the bridges are cleanly bevelled, and the open-worked 18K gold rotor borrows its shape from the oscillating weight of the very first Fifty Fathoms from 1953, tying the whole lineage together visually.
On the wrist, the watch wears almost exactly like a well-preserved vintage Bathyscaphe, just with modern tolerances. Water resistance stands at 300 metres, so nothing was sacrificed for the retro sizing. Collectors who found the standard 43mm Bathyscaphe line too large have been asking for a watch like this for years, and the room at the launch suggested plenty of agreement that Blancpain got the proportions right.
Availability reflects the limited nature of the release. Production is capped at 300 individually numbered pieces, each delivered in a Peli-style hard case with a five-year warranty, and the edition is reaching boutiques now. Pricing is set at CHF 13,800, which places it deliberately close to the steel Automatique despite the ceramic bezel, the gold rotor, and the exclusivity factor. For anyone who missed the vintage market’s appreciation of the 1968 Bathyscaphe by a decade or two, this is the second chance nobody expected to get.
