Instruments BRS92SISTSCR— lug 20mm

The lug width of the BRS92SISTSCR is 20mm. This measurement is specific to the model and ensures balanced proportions between the 39mm square case and the wrist. Correct measurement is taken between the inner shoulders of the lugs: any strap must be exactly 20mm to fit without friction or excessive play.

For the BRS92SISTSCR we recommend vegetable-tanned alligator for refined elegance, vegetable-tanned calf for natural character, cotton NATO for tactical versatility, or FKM rubber for total practicality. The choice depends on usage: as an aviator's instrument, the model suits both robust, waterproof materials and precious leathers with evolving patina equally well.

The BRS92SISTSCR features an integrated lug system with removable spring bars. To change the strap: (1) obtain a spring bar removal tool; (2) position the tool under the inner lug, compressing the small spring bar; (3) extract the lug from the opposite side; (4) repeat for the other lug; (5) insert the new strap by aligning the lugs with the case holes. Verify that the pins are fully inserted before wearing the watch.

Yes, any 20mm aftermarket strap is compatible with the BRS92SISTSCR. Compatibility is guaranteed by the lug width specification. Milano Straps 20mm straps have been tested on this model and offer superior artisanal quality to original bracelets, with customisation in leather, colour and stitching thread.

Leather strap durability depends on daily wear and maintenance. Alligator and vegetable-tanned calf typically offer 5-7 years of regular use before replacement, developing an ageing patina over time. With proper care (drying after water contact, moderate sun exposure), longevity can extend further. Milano Straps guarantees 18 months on personalised Casati straps.
