Frequently asked questions

What is the lug width of the Longines Heritage L2.694.0.83.6?

The lug width of the Longines Heritage L2.694.0.83.6 is 17mm, a specific dimension for this compact model. To verify strap compatibility, measure the internal distance between the watch's lugs: it must be exactly 17mm. This non-standard measurement requires purpose-made straps, available in the 17mm collection at Milano Straps.

Which strap is most suitable for the Longines Heritage L2.694.0.83.6?

For the Longines Heritage L2.694.0.83.6, we recommend dark brown alligator (seal or moor brown) or Taurillon calf in cognac and burgundy tones. These noble materials enhance the watch's classical identity without aesthetic compromise. Shell cordovan in black represents an equally sophisticated option if you prefer strong contrast with the silver dial.

How do I change the strap on my Longines Heritage?

To change the strap, use a spring bar tool or dedicated removal tool to gently lift the spring bar mechanisms at each lug. Align the new strap's holes with the watch's lugs and carefully reinsert the spring bars, ensuring they are fully secured on both sides. Proceed cautiously to avoid marking the stainless steel case.

Is the Longines Heritage L2.694.0.83.6 compatible with aftermarket straps?

Yes, the Longines Heritage L2.694.0.83.6 is fully compatible with aftermarket straps, provided they respect the 17mm lug width specification. Milano Straps offers a comprehensive range of customisable leather straps, bespoke-crafted at the Casati Milano atelier.

How long does a leather strap last on this watch?

A noble leather strap (alligator, calf, shell cordovan) crafted with vegetable or tannin tanning typically lasts 3-5 years with mindful daily wear. Longevity depends on sun exposure, humidity, perspiration and usage frequency. Milano Straps guarantees 18 months on Casati Milano custom straps, with extended restoration and maintenance services available.
