FAQ
What is the lug width of the Sinn 613.010?
The Sinn 613.010 features a 20-millimetre lug width, a non-standard measurement that requires a strap specifically constructed for this width. Correct measurement involves positioning callipers between the inner shoulders of the attachment lugs, excluding tube thickness.
Which strap is best suited for the Sinn Diving Watches 613.010?
Genuine alligator and vegetable-tanned calf leather provide aesthetic solidity proportionate to the 41mm case. For tactical and marine use, nylon NATO offers practicality and resistance to salt water corrosion. FKM rubber remains the functionally optimal choice for actual diving operations.
How do you change the strap on a Sinn 613.010?
The 613.010 features removable lugs via small spring bars or screws, accessible from the case back. Remove the bars using a dedicated tool (spring bar tool), unthread the old strap, and insert the lugs into the new strap, ensuring the bars snap securely into position.
Can I use an aftermarket strap on this model?
Yes, provided the strap is constructed for 20mm lugs. Universal straps in 22mm or 19mm will not fit correctly; always verify lug width before purchase. Specialised artisans can construct bespoke custom straps.
How long does a leather strap last over time?
A quality leather strap (alligator, vegetable-tanned calf) has a lifespan of 3-7 years with regular use and proper maintenance. Protect the strap from prolonged moisture, apply natural conditioners every 4-6 months, and store in a dry environment. The patina that develops increases aesthetic value over time.
