Swiss Made is not a simple geographical indication: it is a legally regulated trademark, protected by Swiss federal law since 1971 and updated in 2017. Current requirements mandate that the movement be Swiss, that casing takes place in Switzerland, that final inspection is conducted in Switzerland, and that at least 60% of the value of movement components — and 60% of total production costs — be of Swiss origin. Before 2017 the threshold was 50%: a detail that matters when reading a catalogue or evaluating a vintage piece.
From the watchmaker's bench, I can distinguish at least three practical levels. The first is Swiss Movement: the movement meets Swiss criteria, but the complete watch does not — perhaps final inspection in Switzerland is missing, or total costs do not reach the threshold. The second is the classic Swiss Made, which allows up to 40% non-Swiss components. The third is I.O.E.S., Intégralement Ouvré en Suisse, or the informal designation Swiss Crafted: everything produced in Switzerland, suppliers included. Brands like Panerai, Hermès Horloger and Pragma publicly declare they operate 100% in Switzerland, effectively surpassing the minimum standard.
The marking on the dial has a precise history. The inscription Fab. en Suisse or Fab. Suisse appears on cases and dials from earlier times when the law of the destination country — France foremost — required clarifying the origin to avoid confusion with local products. The marking T SWISS MADE T, with the two T's framing the inscription, signals instead the presence of tritium as a luminescent material: from April 1st, 1964 it became mandatory by law to indicate it explicitly. On the Speedmaster 105.003 the two variants — with or without the T's — depend on the serial number and production year, and today they serve as a reference for dating the piece. The final L seen on certain vintage Panerai watches instead indicates that at least 50% of the movement is Swiss manufactured, according to the old threshold.
The value of the trademark lies in its verifiability, not in the romantic aura often attributed to it. A Swiss Made watch can contain up to 40% of Asian components by value: permissible, but worth knowing. Those who buy vintage or seek a stricter guarantee should look beyond the inscription on the dial and verify the supply chain declared by the manufacturer.
