Unique wave dial with applied markers |
The Onda Laguna is where Squale took the old ingredients and made a new recipe out of it. The case dimension stays true at 41mm wide and 48mm lugs to lugs, similar to the Squale 50 Atmos Blue. Boasting a 500m water resistant without the use of the conventional Helium escapement valve due to it's unique case design. The unique case construction also meant that the 500m watch can be kept at a slim 12.5mm. The contemporary footprint means that the 50 ATMOS Onda Laguna is exceptionally comfortable on the wrist. Topping it off, sapphire crystal with anti-reflective coating for added toughness and clarity.

Polished raised markers with matte background |
With the similarities to its precursor, this is where it ends. The Onda takes a whole new aesthetic upgrades that never been seen before in the 50 ATMOS collection. First off, the graduated bezel is now made from stainless steel with polished raised numerals and markers against a matte background. This reminisce of the same style as the bezel found on the Yacht-Master. With this bezel, it not only gives a better marine style aesthetics, but also allows users to enjoy little bit of intangible aspect when they rotate or brush their fingers over the raised markers. Did we mention the making of this bezel is extremely time consuming?

Classic Squale case design |
Another main tweak is to be found on its dial. For the first time, the laguna green dial uses the true-to-vintage applied hour markers, usually found on other Square special/vintage models. The highlight of the dial is definitely its unique wave texture that are engraved on the surface with the Square logo and model name placed nicely on it. The textured dial with faceted hour markers gives the dial a sense of quality and timelessness. It seems to draw a more nautical and oceanic feel, giving the wearer additional satisfaction when glancing at it to see the time(or not).
