Strap for Symphonette M Red Gold / Diamond / MOP

The lug width of the Longines Symphonette L2.305.9.87.0 is 9mm. This dimension, also known as ansa width, represents the distance between the metal lugs on the case and determines which strap is compatible. To verify it, place a ruler between the two side lugs: the resulting measurement must be precisely 9mm for a correct fit without excessive play.

For the Symphonette L2.305.9.87.0 in rose gold, we recommend alligator in black or brown for a classic and durable combination, or vegetable-tanned calf leather in burgundy or cognac if you desire a patina that evolves over time. Shell cordovan is an excellent choice for those who alternate the watch between formal contexts and daily wear. All our 9mm straps are available with personalisation of initials and choice of stitching thread.

To change the strap on the Symphonette L2.305.9.87.0, use a spring bar remover tool (Y-shaped with fine points) to compress the small elastic pin inside each lug. Once the spring bar is depressurised, the old strap slides away easily. Insert the new strap by aligning the keepers with the lugs, then compress the spring bar into the opposite hole until secure. The operation takes less than a minute and requires no special expertise.

Yes, the Symphonette L2.305.9.87.0 accepts any strap with a 9mm lug width, provided it is in good condition. Handcrafted custom straps from Milano Straps offer superior quality compared to factory Longines replacements, allowing you to choose leather, colour and stitching details. Compatibility is guaranteed: the 9mm lug is a universal standard.

A quality leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts an average of 5-7 years with regular use, considering a replacement every 2-3 years if worn daily. Durability depends on the tanning: vegetable leather develops an ennobling patina and can last longer if maintained; alligator maintains its structure over time without aesthetic deterioration. Milano Straps straps include an 18-month warranty and can be lengthened or shortened at any time.
