One look will not allow you to totally figure out how the understated elegance of Blancpain’s sporty Fifty Fathoms Bathyscaphe was created. The watch is named after the bathyscaphe which is a deep-sea submersible.
The military feel is understandable because of the triple-loop NATO strap.
Observe carefully once more and take note of the refined hour markers which are made of gold and are luminescent.
What you might not know is that the graduated scale on the unidirectional bezel is in Liquidmetal. This is an “amorphous metal alloy” highly resistant to deformation which bonds well with the ceramic bezel insert.
One pleasant surprise is the open sapphire crystal case back. Most diving watches would have a closed case back for water-resistance security issues.
Similar to the Fifty Fathoms Automatique of 2007, the Fifty Fathoms Bathyscaphe houses the Calibre 1315 automatic movement.
The Fifty Fathoms Automatique has the water-resistance of 300 metres and a closed case back.
So was the water-resistance level of the Fifty Fathoms Bathyscaphe compromised with an open case back?
It wasn’t simply because the Fifty Fathoms Bathyscaphe is also water-resistant to 30 bar or 300 metres.
What is also intriguing is the claim of being anti-magnetic; after all, watches with anti-magnetic features typically have closed case backs.
One explanation for this feature in Blancpain’s Fifty Fathoms Bathyscaphe being the use of the non-magnetic silicon balance spring (which is not used in the Fifty Fathoms Automatique).
For us, Blancpain’s Fifty Fathoms Bathyscaphe is an understated elegant sports watch with an open back that offers more “depth” so to speak, allowing one the pleasure of viewing its movement – the Calibre 1315.
