Swatch – Hands-On with the Sistem51 Petite Seconde
A timeless marvel of automatised watchmaking gets a subtle treat
The Swatch Sistem51 is a revolutionary mechanical watch in many ways. The outside-the-box thinking required in its creation is a bit lost when you look at it, however, getting closer and you realise that there are lots of audacious solutions contributing to a watch which the years before was unthinkable: an really affordable mechanical watch, stylish, entirely swiss made, from a maker of high repute and recognition, precise, with long power reserve, and free from any of the usual quirks of owning a mechanical timepiece (for good or for bad).
Today, the watch gets a significant, in my opinion, update: next to the original central seconds, the new Petite Seconde version gets a – well – small seconds at 6 o’clock:
I well remember the peculiar sensation when strolling the halls of BaselWorld 2013: for the first time, not a super complicated piece, a new Rolex Submariner or a handcrafted artwork at the AHCI booth dominated the chatter in the corridors; it was a humble, plastic watch costing below € 150 – a Swatch of all brands! When Swatch Group president Nick Hayek entered the stage of a press conference at he was certain he had a sensation to announce: a new mechanical Swatch, an automatic one (of course at this market segment!) with an impressive 90h of autonomy, and one which was built in revolutionary, fully automatised assembly line: the Swatch Sistem51.

With the Sistem51 (the -51 refers to the number of its individual parts) Swatch once more reminded us what a game changer the brand was: with the original plastic quartz Swatch, a daring gamble unfolded into a tremendous success: instead of a mechanical wonder piece, Nicolas Hayek Senior decided to put Swiss watchmaking back into the minds of the consumers worldwide using a cheap watch made by robots – but stylish and a ‘must have’ piece.
The Swatch was an instant success, and quickly developed into the watchmaking equivalent of a Volkswagen Golf: practical, reliable, versatile, an icon that defies categorisation.
ETA, mainly responsible for the technical implementation, used a concept formerly tested with the slimmest watches ever produced: The Concord Delirium, one of them, was only a remarkable 1.98 mm thick, a world record, made possible through the use of the case as movement plate as well. The Swatch did the same, but not for the sake of saving µm, but for the sake of economising production and assembly. And it became an icon of pop culture, a single product which put Swiss watchmaking back on the map!
Fast forward, with the advent of electronic gadgets and smartphones attracting the youngsters, Swatch reckoned it was time for another such splash: creating an affordable mass-produced mechanical watch. But the time was running, as the grapevine had it that – again! – the Japanese were working on similar.
(ETA is again technical mastermind behind the Sistem51)
To save on time, ETA, again technical leader for this project, decided to develop watch and the respective production machinery in parallel. The Swiss engineering industry condescendingly dismissed the prospect, but a precision machine specialist SME from the German Black Forest region took up the challenge, and together with ETA succeeded.

Enter the Swatch Sistem51! As hinted above, there are a number of technological feats built into the watch, mainly the movement – more on this in a bit. The initial version came in a plastic case with a sweep central second, and a modern, distinctive design. Another distinctive feature was the noise…
Eventually, Swatch would also offer a metal case (the ‘Irony’ model, pun (I guess) intended…), and a few weeks ago a mechanically modified version came to light: the Sistem51 Petite Seconde:
Not surprisingly this one replaced the central seconds with a small second at 6 o’clock. But this was not the only change.
The designers at Swatch also opted for a distinctly classic yet sporty and bold dial, with a central area in a light blue sunburst finish (which appears much lighter than the press images suggest) framed by an (embossed?) circular grained chapter ring for the applied indices, and a finely brushed one for the seconds display.
Overall, a quite characteristic presentation, particularly in sided light:
Certainly, this appears to be a comparatively luxurious specification for a watch slightly south of € 200, and the cost saving measures are clearly laid open: the central dial area rather looks like finished with your kids’ old water colour kit (it is a bit coarse and lacks the glow of much higher priced watches), and also the seconds hand sits highly above the dial such as to provide sufficient clearing for the rather rougher robot-facilitated settings of the hands:

Overall, this has to be seen in context, and given this, I am clearly more than d’accord with what I have seen…
I mentioned unusual technologies several times already, and also the noise… time to look at the back:
The movement, a slow beat automatic engine with a pace of 21,600 vph offering a solid 90h of power reserve, is key to the entire watch:
Apart from the rather strange bridge decoration, it breaks with a number of rules broadly adhered to in watchmaking: it makes compromises usually not accepted for the sake of keeping costs down, and here this means manual labour: like the case, dial and hands also the movement is made practically without human interference.
To make this possible, ETA rethought a great number of processes, e.g.:
- The entire movement is made from an alloy called ARCAP (composed of copper, nickel, and zinc), intrinsically anti-magnetic, taking away the need for adjustments later.
- Balance and hairspring are laser-poised and laser-regulated during production, there is no need to regulate it later (it is also not possible); prerequisite for this is (1)
- The bridges are no longer screwed to the mainplate, they are laser-soldered in place (this makes servicing the watch impossible: if you disassemble you destroy the movement)
- There is one single screw attaching the rotor, and the ball-bearing used makes quite noticeable noise when worn
