CoLAB Sous-Marine

Step 3: Results in 3D and technical details

CoLAB – Airain Sous-Marine

Help us shape Airain’s next flagship

The first 3D images surface. Discover the smooth new looks and what’s under the bonnet of the reimagined Airain Sous-Marine.

In the previous steps, you helped us decide on things like the type of glass, second hand shape, the diver graphic and placement of the Fab. Suisse tag. We also provided some background information on the parmentier crown, for which we have some exciting news. 

This round, we’re adding a few Quick Polls and we’ll be reintroducing an old acquaintance. And there may be a pre-order update, too…

Meet the New Sous-Marine

Voting Results

Tallying up the scores

It’s always exciting to see the numbers rise over time. Some features really elicited some strong opinions, which have really helped us shape the new Sous-Marine.

The seconds hand design poll left no doubt about your preferences: a whopping 74% of the votes chose the French lollipop design over the DNA strand seconds hand. Roughly the same number of votes (73%) went to the ‘diver with spear’ graphic on the caseback, even though there were three options to choose from here. The placement of the Fab. Suisse tag was even more unanimous: 77% of the voters did not like the tag centre-stage under Airain’s logo, and wanted it tucked away below the six o’clock mark.

About the Glass

Let’s dive right in. In the first step, we established that 53% of your votes selected acrylic glass. But during the technical development we discovered that if we want to guarantee a water-tightness down to 200 metres with acrylic glass (which was this new watch’s primary aim), we cannot keep the original looks.



It’s a different thing with sapphire glass, which DOES work in the original shape at a depth of 200 metres. So, we decided to prioritise the original’s looks, which means the Sous-Marine Re-Edition will have sapphire glass. The only 3% majority of the votes makes this decision a little easier.

Improved Parmentier Crown

As explained in the previous step, the original Sous-Marine was watertight to a depth of 200 meters thanks to the Parmentier crown. The original crown had one major disadvantage, though: it would easily come off and get lost.

To honour the original’s looks, the new Sous-Marine will also feature the Parmentier crown. To make sure it won’t fall off as easily, we’ve improved the attachment system.

Proof of the pudding is in the eating though, and we will not know how effective our design update has been until someone starts wearing our Sous-Marine regularly. We’re currently investigating the possibilities of adding a spare crown cap to every order, or whether you can easily re-order a lost cap if necessary.

Last but not least, we will also add a waterproofing barrier inside the winding crown, providing water resistance of at least 30 meters even without the crown cap!

Reintroducing: The Fixoflex® bracelet

The iconic watchband, that sold over 100 million pieces, is back

Small drumroll please, because we have a soft announcement:

We’re happy to share that we’ve revived Fixoflex, the famous bracelet brand! As part of the ROWI company (Rodi & Wienenberger), their bracelets were top of their class from the 1960s through to the 1980s. But as finding investors proved increasingly difficult for them, ROWI eventually folded in 2019.

To stay true to history (remember the poster in Step 1?), our new Sous-Marine will, once again, have custom Fixoflex bracelets, with a first link specifically designed for the Sous-Marine. Isn’t it wonderful to see two major players reunited? Who knows, maybe we will also re-introduce Fixoflex as a match for other watch models. What do you think?

The Watches

We absolutely adore the results. And you?

We love how the new Sous-Marine came out. Its non-compromising, functional design makes this watch a perfect fit for any tool watch lover. And regardless of your colour preferences, the clear hands and dial numbers are easy to read under any circumstance.

Behind the Caseback

Flagships need strong engines

A sophisticated movement is what turns a watch into a legend. That’s why we cooperate with Manufacture La Joux-Perret from La Chaux-de-Fonds in Switzerland. They will create the new Sous-Marine’s movement dubbed ‘AM5’, based on their G100.

The Swiss-Made AM5 self-winding mechanical movement boasts an impressive 68 hours of power reserve. Its solid tungsten rotor ensures a smooth rotation and weight distribution while its accuracy is regulated to no less than 4 positions. It is finished in ‘Soigné’ with blue screws.

As a well-established Swiss movement manufacturer, La Joux-Perret is our supplier of choice. Their AM1 and LC-450 movements were the driving force for our Airain Type 20 and Lebois & Co Heritage Chronograph.

Pre-order Round 1: Early-Bird Benefits

We reward your early commitment!

Because the technical development has already taken place, we will move into the prototype phase as soon as we have processed your feedback. At that time we will also start the first of two pre-order rounds. The second pre-order round will follow after the prototypes are finished. In return for your trust and early commitment, the first pre-order round offers the biggest advantage compared to the final retail price.

Oh, and remember the vintage poster that inspired us to revive the Sous-Marine? We decided to start reproducing it and offer it as an extra to anyone who participates in the first pre-order!

BONUS: Collect CDMLEC Rewards with your purchase

Pre-ordering your Sous-Marine now comes with an added benefit. In the next couple of weeks, we’ll be rolling out a new loyalty programme to reward future AND past buyers of Airain products (+ CDMLEC’s other brand, Lebois & Co).

Through this programme, you automatically build up points for every purchase at one of CDMLEC’s brands. You can check out the first details on our dedicated Rewards page, which we’ll expand soon. For now, the most important thing to note is that loyal fans will enjoy more benefits in the future!

Pre-order Round 1 opens 9 December at 10am CET








Next Step: Prototyping

What’s next?

Yay! This is where it gets even more exciting. With your final feedback, it’s time to start the actual prototyping. Over the coming weeks, we will start production for the first Sous-Marine samples.

We cannot wait to get our hands on this thing! When we do, we will be back in the next CoLAB step, with undoubtedly amazing video and picture footage of our joint creation.

Quick Poll
