subino 3920 case

whatawatches.com




Last February, we visited the Squale SA headquarter in Switzerland. We designed the dial, case, accessories, packaging and signed a Memorandum of Understanding (MOU) to bring the product to the global market.




We decided on reference number 3920 for our case design which was designed by us. We wanted to incorporate our philosophy that we learned throughout the years into this design. We reduced the lug width and ergonomically adjusted the position of the lug hole so the spring bar is not too far or close to the case for perfect strap changes. We even 3d printed out the case in advance and wore it on our wrist to test every aspect of the watch.



















The second alteration was performed on the lug length. After many trials of testing, we realized by reducing the lug to lug size and the position of the lug hole from its international release made the lug to lug hole to be just close enough to the case to a nice strap on without having the strap rub against the case. This intentional change made the watch look great on any straps.

Lastly, we wanted to change the transversal angle of the lugs’ arch by 1 degree to an extent that it is unnoticeable in the eyes of the customers. However, we concluded that we would be deviating too much from the original case design and take away the beauty from the big head bezel and mid-case proportion design that Squale is known for.












The first alteration from the original Subino 39 case was performed on the lug width. We reduced it from 22mm to 20mm. Considering that the original case had a diameter of 35mm and a lug width of 18mm, 21mm would be proportionally right. However, 21mm is hated by many enthusiasts for its uncommon size. For the easy strap change, most prefer the lug width of 20mm. With this small, but impactful change, owners can enjoy different strap options as this watch is a strap monster.





high quality spring bars

everestbands.com





We carefully selected the spring bars that are most fitting for our newly designed case with ergonomically placed

lug holes. For casual buyers, the spring bars seem unimportant, but here at Whatawatch, we wanted a perfect size to

match our improved design. We realized that solid proportionally thick spring bars made the straps fit onto the case perfectly

without any play. After many trial tests, we decided on 20mm width spring bars with a thickness of 1.8mm and end pieces size of exactly 0.9mm for a snug fit.

We have seen various types of watches but only a few brands put this amount of attention to details on getting the spring bars just right for the case. Good-quality spring bars are fundamental to strap replacement. To maximize our enjoyment of the watch, every aspect of the watch must be utilized properly including the spring bars.

The spring bars that are provided for Corso watch are from Everest Horology. They are the only manufacturer of spring bars that has a similar quality to Rolex. We haven’t seen any aftermarket spring bars that are better fitting on our Corso watch.

Generally, spring bars are not part of the customer's key point to purchase. If this contrapositive is true, then a spring

bar is a component of the watch that we can cut down on the cost. However, we believe in attention to detail

and quality products so we invested in the finest spring bars that we could find.




no-date dial

whatawatches.com




The dial was inspired by the 1960s watch that targeted french civilians by LIP, equipped with a Subino case. The isosceles triangular shape markers with sharp piercing tips bring unique symmetry to the dial. Nowadays, dials with the Date function are common. However, in a timeless vintage design, we believe a simple and symmetrical watch dial design appealed to us more than the benefits of the date complication on the dial. In the end, we chose triangle markers on a dial without a date to capture the vintage feel of the 1960s. Maybe Corso will be the first and only dive watch with a triangular marker dial that our customers have throughout their watch collecting journey.







shell cordovan leather

horween.com


For the strap, we used leather from Horween Leather Co. in Chicago, USA. Shell cordovan from Horween is made with an authentic method and only a small amount can be produced at a time. We are certain that the owners of Corso will love our unique strap design and feel. Korean artisan 'Edd Fitters' will make the straps.

The beauty of Horween’s Shell cordovan comes from the freckled stains with unique colors on the strap. The leather ages beautifully with use and it will hug the owner’s wrist with time. It is designed for a vintage look and is resistant to moisture.

All our Horween’s Shell cordovan are handmade straps. Unlike other workshops, we do not add leather to the inner part of the strap to change the overall aesthetic. We only use the Horween leather as it is even if it is a little thin.









acier tropic buckle

whatawatches.com


We named the buckle TROPIC, it is the acier buckle for dive watches. It was originally designed and used in the 1960s. The workshop that made this buckle had disappeared and it is impossible to acquire an authentic buckle. To solve this issue we sought after a factory that can make buckles using a traditional manufacturing method instead of manufacturing it by CNC system.

What we look for is a vintage look and feel for the buckle and that is why the buckles were not cut perfectly by the Computer Numerical Control system. They were pressed and made through a traditional method. This is why every buckle is not the same with some corners round and irregular.

We used the old method of drilling holes on the buckles and designed Push-type shoulder-less spring bars to fit the buckle like a glove. The taper of the leather strap is beautifully executed from 20mm to 16mm. With a tapering high-quality leather strap, your wrist will comfortable with a sophisticated look.












marine nationale nato (optional)

erikasoriginals.com


We optionally provide the MN Nato strap for the watch. It was made from parachute bag straps that were used during the Wars by the French Marin Nationale(MN). This strap is very comfortable and securely holds the watch on the wrist with its elastic fabric materials.



The strap is a collaborative work with Erika’s Originals based in Spain. We chose a buckle to be brushed to match the tool watch aesthetic and asked Squale for permission to use their logo on the buckle to match the watch. The color of the strap we chose is Sahara desert color for a unique look that matches ‘Corso’ collection. This Squale strap is exclusive to our shop.



'hinoki' portable watch case

toyocraft.com















For this collection, the packaging was co-produced with Toyooka Craft Japan. Mr. Yamazaki Toru, the CEO of Toyooka Craft commented that in a Private Rolex Museum in Japan most of the original boxes for the vintage Rolex are usually non-existent. However, they provide the highest quality wooden watch case to hold the special timepiece inside. We wanted to bring this kind of attentiveness to our products.


The Corso portable watch case is exclusive to our shop and it is made of a special wood called ‘Hinoki’. We only used the highly demanded bottom part of the cypress tree, which is regarded to have the highest quality of wood. A translucent black lacquer was applied 4 times with the traditional Japanese lacquer technique. This brings out unique patterns and reflections under natural light.


Hinoki wood emits a naturally antibacterial phytoncide scent. It will be more durable than your average wood case. In Japan, the bottom part of the Hinoki wood is considered to be the best in the country. The quality of the wood is at such a standard that the Japanese woodworkers will cringe at applying any lacquer over the Hinoki wood.


With investment from the Japanese government, Toyooka Craft developed a special lacquer painting technique on Hinoki wood. This took 4 years to develop, but it was well worth the trouble as the special lacquer technique allows the color to sink in with the slight translucent property.
