Strap for Spirit 26.5

The lug width of the Longines Spirit L2.196.4.23.2 is 13mm. This measurement corresponds to the internal distance between the case lugs (spring bar seats). To verify, measure with a digital calliper the space between the lugs: the result must be exactly 13mm. This dimension is non-standard and relatively rare in the market, making the model particularly suited to bespoke strap solutions rather than mass-produced alternatives.

The ideal strap depends on usage and season. For formal wear, we recommend alligator in black or cognac with vegetable tanning, which enhances the watch's aviation heritage. For everyday elegance, Swiss calf leather with vegetable tanning develops a natural patina over time. For versatility, a NATO strap in anthracite grey or dark blue offers lightweight practicality. In summer, a nitrile or fluoroelastomer rubber provides thermal comfort. All materials must accommodate the 13mm lug width specification.

To change the strap, obtain a spring bar removal tool or consult a watchmaker. Access the lower lug of the case and locate the internal tension spring. Apply gentle pressure to release it, then extract the old strap. Insert the new 13mm strap into the lug space, then reinsert the spring until it clicks into place. Verify that the strap is securely anchored before wearing the watch. If uncertain, entrust the operation to a professional horologist.

Yes, online retailers stock 13mm-compatible straps ready for dispatch, customizable in length, initials, and thread colour. MilanoStraps offers a curated selection of certified leathers (alligator, calf, NATO, rubber) pre-cut for 13mm lugs. For an integrated luxury experience, the Casati Milano atelier creates bespoke straps with personal leather selection, WhatsApp progress updates, and an 18-month workmanship and material warranty.

Longevity depends on material and usage patterns. An alligator strap with vegetable tanning, with daily care (drying after moisture exposure, dry storage), lasts 3–5 years. Swiss calf leather offers similar durability, averaging 3–4 years. Leather develops character-rich patina over time. Factors that reduce lifespan include prolonged moisture exposure, excessive heat, and frequent perspiration. A nitrile or fluoroelastomer rubber strap remains functional for 5–7 years. MilanoStraps guarantees 18 months on any bespoke strap produced by Casati Milano, covering manufacturing defects and material faults.
