This watch includes the Squale Wooden Limited Edition watch case. Extremely rare, 100 pieces made, sold out .The watch comes with a special wooden presentation box and a diving knife. 

The 1521 features a 41.5mm case by 48.5 lug to lug and a total thickness of 13mm. The case is high polished and features a sunken in crown by the 4 o’clock position. This allows the crown to be protected from knocks and damages while under water. The high contrast yellow hands allow the watch to be more visible in darker depths of the dive.

Just in case our clients decide to take this timepiece on a serious dive, Squale has equipped this with 500 meters of water resistance. Alongside the timepiece, we also equipped our divers with another extremely useful tool. A Fox Tactical Fixed Blade Knife made in Italy to compliment Squales Italian heritage. Nitrox is an effective tool that enhances the experience of recreational diving & reduces the possibility of decompression sickness.

Its purpose is to increase a diver’s bottom dive time to enjoy longer dives with shorter surface intervals. Enhancing the luxurious experience. Pairing Nitrox with our luxurious & capable limited edition Squale 1521.

Enriched air nitrox also known as (EANx) refers to any nitrogen/oxygen gas mixture with more than the 21 percent oxygen found in normal air. Enriched air has more oxygen than air does, that reduces the portion of nitrogen. As a result, you puff less nitrogen during the entirety of the dive than if you’re utilizing routine air.

Water pressure causes nitrogen from the air the diver is inhaling causing bloodstream and tissues to dissolve As the diver goes deeper, the pressure increases which allows more nitrogen to dissolve in.

A surplus of dissolved nitrogen in their tissues can form bubbles resulting in decompression sickness also known as (DCS).
