Strap for Jazzmaster Petite Seconde

The lug width of the Hamilton Jazzmaster H32555755 is 20mm. This specific measurement is essential to ensure optimal visual proportion between the 40mm case and the strap. When purchasing a replacement strap, always verify that it is exactly 20mm wide, measured within the internal cavity of the lug itself.

The best strap depends on intended use. For formal occasions, we recommend quality leather with vegetable tanning (alligator, calf) in dark tones. For daily versatility, a medium brown or black calf offers the perfect balance. For sports settings, a cotton or silk NATO maintains elegance without compromising practicality.

First remove the old strap using a spring bar tool to extract the pins from the lugs. Insert the pins into the holes of the new 20mm strap, then secure them firmly in the case cavities. Verify that the strap is properly centred and that there are no unusual gaps.

Yes, provided the lug width is exactly 20mm. Quality aftermarket straps, crafted with artisanal leather or technical materials, install without case modification. We always recommend specialist manufacturers to ensure precise workmanship and durable materials.

A quality leather strap with vegetable tanning typically lasts 2-4 years with moderate daily use. Durability depends on exposure to perspiration, moisture, and frequency of wear. Proper maintenance—periodic cleaning, drying, and conditioning—can significantly extend the strap's lifespan.
