CoLAB Heritage Chronograph

Step 4: Prototype reveal

CoLAB Heritage Chronograph

We have collected all your wonderful input, votes on all the different aspects that define this watch, and have discussed the results with our Swiss manufacturers. Now it’s time for Step 4 of our CoLAB design effort: presenting the prototypes to you!

You already saw a glimpse of our Heritage Chronograph’s beauty in Step 3’s 3D-renditions, yet nothing beats having one of the real watches in your hands. Its various beautiful dials and brush finishes lend this watch subtle expressions that reflect the tastes of our true connaisseurs. We are delighted to share the first images with you. Let’s take a closer look at the prototypes together now, shall we?

Presenting the Prototypes

Case-backs, bezels and brush types

Apart from the open case back offering a glimpse of their inner workings, what makes these Heritage Chronographs really stand out is their excellent array of finish choices. Some of the surfaces are polished, others circular and straight-brushed or sandblasted. They work very well together to create an intriguing visual spectacle and contribute to our mission to create maximum value for money: quality timepieces with luxury finishes within a market-friendly price-range.

The other nice thing about the Heritage Chronograph is it comes in four dial colours and two bezel shapes. There’s something there for everyone.


We’re also happy to announce that our prototypes have successfully passed the anti-magnetism test as directed by the ISO 764 industry standard. The tests were carried out on September 14th by Timelab in Geneva. This means we can confidently feature the ‘anti-magnetic’ classification on the dial. Another feature that is faithful to the old designs and further underlines the exclusive character of this watch.

Prototype evaluation: the outcome

Prototyping is an essential step in the watch production process. A lot can already be done with computer animations and 3D, but only the real product gives us invaluable insights in the final results. After evaluating the prototypes, here are the things we will change in the final design:

  • After Step 3, it turned out that our proposed crown top finish was not fully possible. So, we have been experimenting with alternative finishes. The eventual finishing will be as shown in the drawing below. On the prototypes shown, the crown top is still polished.
  • Our prototypes currently have prototype movements that contain components that are needed for automatic movements. As our final product’s movement will be hand-wound, the internal components needed for automatic movements will not be featured in the definitive Heritage Chronograph. Also, the final product will feature gold coloured engravings, as shown in the drawing below.
  • The tachymeter scale on the right side of the dial for ref 324.478 will be made more readable. We will change its current horizontally placed digits to numbers that follow the dial’s curve, mirroring the dial’s left side.
  • The sapphire crystal has a small piece of matte on the side. We asked our supplier to polish this too, and make it transparent like the rest of the crystal.
  • The top of the sub-dial hands will have colored cannons to match the hand color.

What’s Next?

  • Now: A final evaluation of the prototypes
    We’re currently checking the prototypes for any inconsistencies or things that seem out of character.
  • Mid October: Pre-order Round 2
    When everything checks out, we’ll be updating this page and opening Pre-order Round 2 halfway October. We know from experience that these watches can sell out quickly. Subscribers to our mailing list will be notified first. If you don’t want to miss out on your chance to own a Heritage Chronograph, be sure to register for one or more models.

    Be sure to keep an eye on this page anyhow!

  • Then: Production
    In the second half of October, our Swiss manufacturers will start producing your Heritage Chronograph of choice. The Heritage Chronograph will be produced in two batches, dictated by the supply of movements. The first batch of movements will be ready mid-December 2022, after which watch assembly can start. We expect to be able to start delivery by the end of February 2023. As soon as we have an idea of the exact delivery date, we will let you know. The first batch will mainly contain orders from the first pre-order round.
    The next batch of movements will be ready in September of 2023, after which watch assembly can start. These orders will be delivered in the last quarter of 2023, with a possible extension to early 2024, depending on the number of orders.

Project Timeline

Like other attentive fans, you may have noticed that we’ve had to adjust the original timeline several times. We see you. During this particular CoLAB, we’ve encountered multiple setbacks, ranging from production problems to worldwide staff shortages. While these are beyond our influence, we would’ve liked the Heritage Chronographs to be in our and your hands by now.

Thank you for your patience and understanding. We hope (and think!) the quality of the end result will make up for some of the lost time.
