Presenting Andreas Strehler’s Long-Awaited Transaxle Remontoir Tourbillon

Andreas Strehler’s Long-Awaited Transaxle Remontoir Tourbillon

It doesn’t take much to realise Andreas Strehler is obsessed with precision. The watchmakers’ engineer is, between creating some of the best third-party movements in the industry, responsible for the most accurate moon phase ever built, for which he’s in the Guinness Book of World Records.

Like most haute horologists, it’s not often he releases something new – meaning that when he does, it’s well worth looking into. In the case of Baselworld 2018, that something was the Transaxle Remontoir Tourbillon.

You might have heard of it already; even if you didn’t get the buzz about it at Baselworld, we’ve mentioned it here before if only as a movement. Now, we have the full watch and it’s everything that was promised.

So what does it do? Well, it tells the time. Nothing more, nothing less. There’s no record-breaking moon phase here, no butterfly-shaped bridges, but there is an intense tour de force of watchmaking.

Essentially, the Trans-Axial brings together three of Andreas Strehler’s key horological innovations, the first of which is the epicyclical mainspring limiter. The limiter is a gear that ensures the power generated from the twin barrels is as constant as it can be – within the bounds of current lubricants, materials and technologies at any rate.

Then, there’s the Remontoir d’égalité, a constant force mechanism. I’m no watchmaker so I’m not about to describe exactly how constant force is achieved; all you as a wearer needs to know is that it maintains accuracy throughout the watches entire power reserve. Where most are more accurate the more energy they have, here that’s not the case – essentially building on the epicyclical mainspring limited.

So you have a constant flow of power to the watch throughout its power reserve which is displayed via the power reserve indication – but that’s not new for Strehler. So he’s gone further, adding on a tourbillon. Most collector’s know what a tourbillon does, offsetting the issues associated with gravity.

So, a consistent power supply, applying the same force throughout its reserves that’s unaffected by gravity – in short, you have as close to a perfect ‘basic’ movement as you can get. It just tells the time – via two hands and a separate jumping seconds indicator – but it tells it flawlessly.

That movement has then been mounted into a typically beautiful case and left to show off what it does without anything as passé as a dial getting in the way. There you have it: the Andreas Strehler Trans-Axial Remontoir Tourbillon.

And if you’re still wondering about what exactly it is the watch actually does… well then, it’s probably not the right watch for you.
