Strap for Terrasport II Cream / Bracelet

The Terrasport M1-37-47-MB features a lug width of 20 millimetres, measured centre-to-centre between the two spring bar holes. This is an uncommon, non-standard specification that requires careful sourcing of straps dimensioned precisely to 20mm to ensure proper fit and prevent excessive play or damage to the lug.

The Terrasport pairs exceptionally well with alligator straps finished with vegetable tanning or shell cordovan leather, both of which develop character over time and complement the Saxonian austerity of the case. Alternatively, a high-quality calf leather strap with hand-finishing offers suppleness and refinement. For active use, a well-constructed rubber strap maintains the versatility of this instrument watch.

Strap replacement involves removing the spring bars connecting the lugs to the case. Using a dedicated spring bar tool or extract, apply gentle pressure to the spring bar from the opposite side to release it. Position the new strap onto the lugs and reinsert the spring bars, ensuring the fit is secure with no anomalous play.

Yes, aftermarket straps of proven quality are compatible, provided they are dimensioned precisely for 20mm lug width. Specialised artisanal manufacturers offer solutions in natural leather or synthetic materials that maintain aesthetic coherence with the watch's Saxonian design. Always verify exact compatibility before purchase.

A high-quality leather strap, particularly one finished with vegetable tanning, typically lasts 5-7 years with daily wear. Longevity depends on leather quality, care (avoid prolonged moisture and perspiration exposure), and frequency of use. Shell cordovan and alligator are renowned for ageing elegantly, developing appreciable patina over time.
