Blancpain has unveiled a limited-edition timepiece to commemorate the 70th anniversary of the "Fifty Fathoms Bathyscaphe" collection.

It features a glass-box-shaped sapphire crystal, a Blancpain logo from the mid-20th century on the dial, and hour and minute hands and indices painted with vintage-colored Supermilova, giving it an appearance reminiscent of classic models.

 The Blancpain Fifty Fathoms Bathyscaphe, released in 1956, was a diver's watch designed for a wider audience, in contrast to the more professional-oriented Fifty Fathoms. Its proportions, in particular, were slim and understated, making it easy for everyday wear. Since then, it has been continuously refined as a timepiece that combines reliability as an instrument with elegance.

Blancpain "Fifty Fathoms Bathyscaphe" Ref. 5903 1110 63A
Automatic movement (Cal. 1150). 28 jewels. 21,600 vibrations/hour. Power reserve approximately 100 hours. Stainless steel case (diameter 37.40mm, thickness 12.30mm). 30 ATM water resistance. Limited edition of 300 pieces worldwide. 2,299,000 yen (including tax).

 This model, commemorating the 70th anniversary of the Fifty Fathoms Bathyscaphe, is a revival model that reinterprets the design codes of the 1968 model from its entire collection in a modern way.

 The case, with the same 37.40mm diameter as the original model, boasts modern specifications including 30 ATM water resistance. Furthermore, a redesign centered on the movement has resulted in a slimmer silhouette and improved comfort on the wrist. The sunburst-finished Meteor Grey dial also faithfully reproduces the color scheme of the time, with a brand logo reminiscent of the mid-20th century and baton-shaped hands and indices coated with vintage-colored Super-LumiNova.

The bezel retains its former ring-shaped structure, leading to the base of the glassbox-type crystal. However, the original black Hesalite insert has been replaced with a lacquered ceramic insert that offers superior durability and legibility.

 Despite its strongly vintage appearance, its specifications are true to modern standards. It is equipped with the in-house Cal. 1150 movement, which boasts a power reserve of approximately 100 hours, and the use of a silicon balance spring ensures high magnetic resistance and long-term stability.

 This limited edition model, with only 300 pieces available worldwide, features a serial number and the word "70th" engraved on the case back, as well as a special Peli M case.

The transparent case back allows you to admire the high-quality finish of the movement and the 18K gold openwork rotor. Naturally, this is a feature not seen in previous Bathyscaphe models.
