Strap for Parallax Tourbillon

The lug width of the Parallax 1912 is 19mm, measured between the centre of the two mounting holes on the spring bars. This dimension is standard for watches of this case diameter category (43mm) and determines compatibility with any aftermarket strap or bracelet. To verify compatibility, measure the horizontal distance between the lugs: it must correspond exactly to 19mm.

For the Parallax 1912 we recommend a genuine alligator strap with vegetable tanning, cognac brown shade, which emphasises the contemporary sophistication of the case. Alternatively, a brushed smooth calf leather strap in dark burgundy offers discreet elegance, whilst a grey-talupe NATO strap permits practical versatility. The choice depends on usage: alligator for formal occasions, NATO for daily wear. All 19mm straps in our catalogue have been tested for dimensional and structural compatibility.

Strap replacement is accomplished by extracting the spring bar (lug pin) from the lateral seats on the case. Use a spring bar removal tool to compress the internal pin and release the lug. Gently withdraw the pin, remove the worn strap, position the new strap (ensuring it is 19mm width) and reinsert the pin until the locking click is felt. Do not force: the Parallax 1912 uses standard spring bars, but construction precision demands careful movements.

Yes, any strap with certified 19mm lug width is compatible with the Parallax 1912. Our artisanal straps are specifically tested for this measurement and available in alligator leather, vegetable-tanned calf, shell cordovan, NATO and fluoroelastic rubber. Compatibility is guaranteed by standardised spring bar dimensions; however, we recommend verifying that the mounting seats show no excessive wear before installation.

A high-quality leather strap (alligator, calf, shell cordovan) typically lasts 3-5 years if properly maintained: avoid prolonged water immersion, protect from intense direct sunlight, apply conditioning balm every 6-8 months. Actual lifespan depends on frequency of use, climate and care: under optimal conditions, a vegetable-tanned alligator strap may exceed 5 years, whilst brushed calf requires greater attention to constant flexion points. We recommend maintaining a replacement strap to preserve the aesthetic integrity of your Parallax 1912 during the replacement cycle.
