“Squale 1521-026 ONDA 50 Atmos Blue. Designed for the professional diver. The classic 500 meter professional diver with the characteristic and famous “von Büren” case. A case that was part of lots of famous dive-watches over the decades, as Squale supplied these also to other big and small Swiss brands. A recognition for the sheer quality of engineering and timeless design by Squale founder: Charles von Büren.

This unique and highly recognizable shape features a signed screw-down crown on the 4 o´clock position which is recessed and well protected against unwanted impact. Due to the recessed crown and the elegant flowing design of the polished case the watch is exceptionally comfortable to wear even on a smaller wrist. The blue-coloured waved lacquered dial with applied luminescent markers is stunning.

Smooth, ‘coin-edge’ 120-click uni-directional bezel. The scratch-resistant flat sapphire crystal is enhanced with anti-reflective treatment on both sides and protects this timepiece up to 500 meters below sea-level or 50 atmosphere of pressure. The great attention to detail and quality is easy to see in the acid-etched case back. Great details all around that give this iconic timepiece a contemporary look and feel but still paying respect to its classic, unique design and brand philosophy.

The Swiss Made ETA 2824 automatic movement gives the watch its mechanical reliability and accuracy under the toughest circumstances. A purpose build tool-watch which is elegant and reliable, a perfect companion for every day adventures.”
