Strap for Conquest Chronograph Automatic 44.5mm Silver

The lug width of the Longines Conquest L3.697.4.76.6 is exactly 22 millimetres. This specification is determined by the case construction geometry and allows the strap to pass under the attachment terminals without lateral slippage. It is recommended to verify the measurement by positioning a digital calliper perpendicularly to the case plane at the level of internal contact points, as measurements taken on external edges may generate errors of ±1-2mm.

The choice depends on usage and aesthetic preferences. For a formal-elegant pairing, an alligator crocodile leather vegetable-tanned in taupe brown or black enhances the case proportions. For versatile daily use, English calf leather crafted with vegetable tanning offers comfort and durability. For maritime environments or intense activity, a synthetic canvas NATO or vulcanised rubber strap ensures longevity and practicality. Shell cordovan represents the pinnacle of sophistication but requires constant maintenance in humid climates.

The Longines Conquest L3.697.4.76.6 features fixed lug attachments on the case without an integrated deployante. To change the strap, remove the previous strap using a dedicated tool (spring bar tool) that allows the retaining spring to slide sideways. Once the spring is extracted, the strap slides off the terminals. Insert the new strap by aligning the hole in the lug with the terminal and return the retaining spring to position. Verify that both sides are secured symmetrically before wearing the watch. If uncertain, contact an official Longines service centre or a specialised craftsman.

Yes, all straps manufactured to 22mm technical specification are compatible with the Conquest L3.697.4.76.6, provided they respect the construction tolerance of ±0.2mm. High-quality aftermarket straps crafted by specialised artisans often offer superior material and finish choices compared to original Longines straps. It is essential to verify with the seller that the strap has been correctly measured and that the spring bar attachments are of the correct length for the Conquest. Be wary of generic 'universal' strap offers at very low prices: precise compatibility is crucial to preserving case integrity.

A high-quality leather strap, crafted with vegetable tanning, preserved with care and worn in rotation with other watches, can last between 5 and 10 years before requiring replacement. Alligator leather is particularly resistant and can exceed 10 years with regular maintenance (gentle cleaning, conditioning with natural oils every 6-12 months). English calf leather has an average lifespan of 4-7 years. Factors that accelerate degradation include: continuous exposure to moisture, salt perspiration, extreme temperatures and lack of rotation between multiple straps. A NATO strap or rubber strap guarantees significantly longer lifespans (15-20 years) as synthetic materials do not deteriorate through moisture absorption.
