Perrelet
Turbine A1064/4— lug 20mm

The Perrelet Turbine A1064/4 is equipped with lugs measuring precisely 20mm in width. This dimension is determined by the geometry of the 44mm case and the depth of the lug holes. To verify compatibility with an aftermarket strap, measure the internal distance between the two lug holes on the case: it must be exactly 20mm. Any deviation of half a millimetre compromises fit and security on the wrist.

The ideal material depends on intended use and dial colour. For formal elegance, vegetable-tanned alligator in cognac or black tones amplifies the sophistication of the chromed case. For daily wear, textured calf leather offers durability and a fascinating patina as it ages. For sports or humid environments, FKM rubber is the optimal choice: it provides superior grip and longevity whilst contrasting nobly with steel. Canvas NATO straps represent the radical sports option, particularly coherent with the 44mm diameter.

The Perrelet Turbine A1064/4 features a standard attachment system with removable spring bars. Equip yourself with a dedicated strap removal tool or fine-pointed implement, work on a protected surface, and gently press inward on the small groove of the spring bar to free the end from its seat. Repeat on the opposite side. The operation requires patience and precision to avoid scratching the case. If you lack confidence, consult a professional watchmaker: the intervention is quick (10-15 minutes) and often complimentary if performed at the retailer.

Yes, all straps engineered for the 20mm lug width are mechanically compatible with the Perrelet A1064/4, regardless of manufacturer. The true challenge is aesthetic compatibility: because the case is rather substantial (44mm), the strap must exhibit adequate thickness (minimum 3.5-4mm) and precise 20mm width to avoid disproportionality. Partnering with specialised artisans ensures the strap is constructed to appropriate proportions with materials that dialogue visually with the brushed or polished stainless steel case.

Leather strap longevity depends on material and usage patterns. Premium alligator with vegetable tanning, worn daily in indoor contexts, typically lasts 4-6 years before replacement becomes necessary. Frequent exposure to humidity, UV radiation and temperature fluctuations drastically reduces this estimate. Robust calf leather endures 3-4 years under moderate daily use. Conversely, FKM rubber is essentially unlimited: it resists saltwater, chlorine and UV radiation without significant degradation. To maximise strap lifespan, avoid wearing the Turbine whilst showering, swimming or at the seaside if equipped with leather.
