Previously launching a limited edition to just 150 pieces- the 60th-anniversary special edition that is not just a mere re-issue with much of vintage touches but based on the very first model design manufactured in the 60s.

Right now, for those who have missed the limited editions and craving to get one still, it is your lucky day. Gnomon would like to present to all of you the Squale Sub-39 Marina Blue- sets forth to be more than a favorite among Squale’s fans but as a celebration of how far Squale themselves have come. Now, let’s take a closer look at how Squale is in continuation to mark their diamond anniversary.

Squale Sub-39 Marina Blue

Mentioned above, the Squale Sub-39 Marina Blue, derives from its oceanic blue sunburst dial. Inspired by the first dive watch model that Charles von Büren created in Neuchâtel, Switzerland, is more than meets the eye.

Everyone who is into dive watches would remember this watch brand has supplied some of the most famous watch companies in the world. The Sub-39 is the tribute of the BP’s 1960s legendary Fifty Fathoms Bathyscaphe diver that utilized Squale cases, during the Swiss watch manufacturer Rayville’s period.

Bathyscaphe, the name came from the submersible cabin in which divers used to the deep ocean.

The original was inspired by a famous Swiss explorer named Jacques Piccard, who descended into the Marianas Trench during the 60s in the Bathyscaphe Trieste with another partner, Don Walsh.

Therefore, Bathyscaphe bears one of the most critical dive watch designs in history, and Squale’s involvement made it possible.

This specific 60s styling cues seen on the new modern tribute, size up from 35mm to 40.8mm (inclusive of the bezel) wide diver with sharp distinctive lugs design with 300m water-resistant. Do not let the muscular lugs design spook you, the Sub-39 is svelte with a height of 12mm thanks to the unique case construction. It bears a slim mid-case (39mm wide), just like the very first design.

Starting from the top, the bezel ode-to-past, using a unique crystal glass insert to mimic those days bakelite material, with the exact old-school 15 minutes markers indicators. Further. Its bezel grooves are right to its kind, thin and intricate, while still comfortable for one to rotate. The unique design has a satin-finished midsection that elevates the bezel from the mid-case, giving it an original look from most dive watches.

Now to the mid-case, it has thick masculine lugs that feature several bevelling, done in full polished that showcases the traits of Squale manufacturing. Also, resulting in addition to a beautiful retro-ish look. Although the lugs are thick, they narrowed into the middle of the watch, total up for the lug to lug dimension of 48.5mm results a good balance bow-of-porridge for many of us on the wrist. Finish up with a period-correct sterile srcew-in “big crown” at 3 o’clock for a tranquil time setting.

Oh, we also do know that this distinctive case most definitely inspired the following Ref. 1521 50 Atmos case design after it, as they do share similar mid-case styling.

Onto the dial side, we have the oceanic blue dial that gets a sunburst effect depending on how the lights hit its surface. Further, nostalgic Pre-60s “Explorer” style layout on a with alternating Arabic and strip markers, all done up in old radium lume that glows green when in darkness. Paired finally with the pencil-shaped handset and arrow second hand, with the same old radium tone. The Squale iconic shark logo further enhances vintage cues at 6 o’clock with the specific “30 Atmos” fonts. Owners can enjoy the whole 60s vibe time-reading through its boxed shaped crystal that is made from sapphire material for durability while mimicking the nostalgic Plexi-crystal found on its precursor.

Another worth mentioning factor would be its unique case back design. Squale designed a unique ring lock system, whereby the case-back secured by a screw-in metal ring on its periphery. This was an ingenious design in the early 60s at that time before adapting to the provened invention of the O-ring rubber seal and screwed-in case-bock combo. The Sub-39 Marina Blue has the exact stepped case-back design (while bears the more efficient screw-in design now), with the correct 60s throwback engravings of its Squale emblem in the middle. With this original remake of its case-back, for us in today’s time, it is a major throwback to authentic dive watch’s construction of yesteryears.

The Sub-39 Marina Blue comes with a 2-piece Handmade Italian leather strap with matching blue color-tone with some handmade texture. The result is a nice touch by Squale to have an excellent backward-looking vibe for a dive watch like this that its design was based heavily on yesteryears.

While somewhat a mark of Squale achievement for the past 60 years. An authentic tribute to its roots as a well-known reliable supplier for others with their dive timing instrument, and lastly, taking pride in that even until today, for us watch nerds.
