Squale 50 atmos 1521 Onda Emerald


The Onda collection is conceived as a tribute to the “sea” which has always been the natural habitat of Squale watches; with a clean line, these watches are dedicated to lovers of the maritime world.

The new Onda dial ('onda' is Italian for 'wave') depicts the motion of waves that transmit harmony and serenity, whilst the dial color is inspired by the natural wonderful colors of the sea.

This is a classic 500 meter professional diver with the characteristic and famous "von Büren" case. A watch case that was part of many famous dive-watches over the decades, as Squale also supplied these to other big and small Swiss brands. A recognition of the sheer quality of engineering and timeless design by Squale founder: Charles von Büren.

The diver has a screw-in case back, and a 316L stainless steel case with dimesions of 42mm x 13mm for a comfortable presence on your wrist. Despite the high water resistance rating of 500 meters the case has been kept to a slim 13mm thanks to the unique case construction.

This highly recognizable shape features a signed screw-down crown at 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 case the watch is exceptionally comfortable to wear even on a smaller wrist. The hand-painted dial with the distinctly designed luminescent markers of Superluminova provides excellent legibility in all lighting conditions.

The smooth, coin-shaped 120 click uni-directional bezel partners well with the orange minute hand providing crucial, at a glance, information on remaining or elapsed dive-time. 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 and the sapphire-crystal guarding the superluminova on the bezel. These details give this iconic timepiece a contemporary look and feel whilst still paying respect to its classic unique design and brand heritage.

The Squale 50 atmos is powered by a Swiss made ETA 2824-2 automatic movement which provides 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!
