Karsten Fraessdorf, the founder of Montres KF, has been a watchmaker since he was a teenager. Restoring old clocks and pocket watches, he learned all about classic escapements and chronometry. Over the past decade, Karsten Fraessdorf has created several watches, and by created, we mean literally created from the ground up with self-developed movements, often showcasing unique escapements and constant force devices. Two years ago, he launched Montres KF and the first watch under his own name, the Spirograph. This year, he introduces his second watch, the Spirograph Sport, a tourbillon wristwatch that you can wear on a daily basis. It has been tested to withstand no less than a 5,000G force meaning that you don’t have to treat it as a regular, fragile tourbillon.

It takes quite some ingenuity to create a watch combining a delicate Tourbillon and daily-wearer capacities!

Today, we’re going to have a closer look at this new Montres KF Spirograph Sport and we’ll meet with Karsten Fraessdorf, behind the bench. There, he will explain all the technical details behind this impressive, innovative and complex watch, by dismantling the movement and the case of this Spirograph Sport, showing all the innovative solutions he created in order to create a tourbillon watch that you can wear every day, everywhere and not have to worry about it. It’s all in the technical-oriented video at the top of this article.

If you want to learn more about Montres KF, you can read our technical review on the first model, the Spirograph, where Frank explains how he’s field-testing this watch as a daily-wearer, without worrying too much about it. It shows what tests have been done, how the watch can resist impressive G-forces and how its movement, calibre 360, was conceived.

Also, you can read this technical article, where we sat behind the bench with Karsten Fraessdorf, looking at all the small details of his in-house, self-conceived, self-constructed movement.

Finally, because it is today’s topic, we’ve done a short review of Karsten’s latest creation, the Montres KF Spirograph Sport, where Xavier explains in detail the Thermo-Compensation system as well as the suspension springs that act as shock absorbers.
