Frequently asked questions
What is the lug width of the Longines Conquest L3.700.4.56.6?
The lug width of the Longines Conquest L3.700.4.56.6 is 21mm, measured between the inner lugs of the case. This dimension is precise and admits no variation: any compatible strap must have exactly 21mm width. On milanostraps.it you will find a complete selection of straps in the correct size, ready for shipment.
What is the best strap for the Longines Conquest L3.700.4.56.6?
The ideal material depends on your use and personal preferences. For formal elegance, black or dark brown alligator represents the most refined choice: the natural texture of the scutes dialogue perfectly with the brushed steel of the case. For a more organic and vintage approach, vegetable-tanned calf offers a patina that evolves over time. For daily sport use, rubber ensures practicality and resilience. At Casati Milano atelier you can personally choose the leather and personalise every constructive detail.
How do you change the strap on a Longines Conquest?
To change the strap, you need to extract the spring bars that connect the lugs to the case. Using a dedicated tool or a delicate implement, slightly compress the spring bar to release the hole and slide off the old strap. Insert the new strap by aligning the lugs to the case holes and release the spring bar. This operation takes just a few minutes and causes no damage to the movement. If you prefer expert hands, the Casati Milano atelier offers mounting and customisation services by appointment.
Is an aftermarket strap compatible with the Longines Conquest L3.700.4.56.6?
Yes, any strap with a 21mm lug width is compatible with the Conquest L3.700.4.56.6, regardless of the manufacturer's origin. Compatibility depends solely on lug width: if the strap is 21mm, it will fit perfectly to the case. The straps from milanostraps.it are handcrafted on request and guaranteed for 18 months when customised at Casati Milano.
How long does a leather strap last on the Longines Conquest L3.700.4.56.6?
The lifespan of a leather strap depends on the quality of the material and daily use. High-quality alligator or shell cordovan typically lasts 3-5 years with regular use, while calf tends to show signs of ageing more quickly—around 2-4 years—but this is often desired for the aesthetic character it acquires. Exposure to humidity, perspiration and UV rays accelerates wear. Straps made at Casati Milano benefit from an 18-month guarantee and can be submitted for extraordinary maintenance to extend their useful life.
