FAQ
What is the exact lug width of the Longines Conquest L3.720.4.72.6?
The lug width of the Longines Conquest L3.720.4.72.6 is 19 mm. This is the distance between the two horizontal pins that protrude from the case. To verify, use a digital calliper positioned between the pins, excluding them from measurement. A tolerance of ±0.5 mm is acceptable, but 19 mm is the official standard for this reference.
What strap type do you recommend for the Conquest L3.720.4.72.6?
The Conquest L3.720.4.72.6 is exceptionally suited to leather straps. We recommend natural alligator for those seeking character and patina development over time, vegetable-tanned calf for versatile sobriety, and shell cordovan for collectors. For a sports dimension, a cotton-stitched NATO strap remains coherent. All must feature a 19 mm lug width.
How do I change the strap on my Conquest L3.720.4.72.6?
Remove the old strap by gently pushing the horizontal pins inward using a flat tool (strap change kit). Once the pins are extracted, the strap is freed. Insert the new strap by aligning the holes with the pins, then reinsert the pins by pushing until they click securely. Verify that the strap is fixed symmetrically on both sides of the case.
Is an aftermarket strap compatible with the Conquest L3.720.4.72.6?
Yes, any artisanal or industrial strap with a 19 mm lug width is compatible. The Conquest does not require special case measurements or constructive adjustments. We recommend ordering a strap with the lug width precisely measured at 19 mm and verifying that the pins are removable for easy changes. Online you will find a wide selection of customisable 19 mm straps.
How long does a leather strap last on the Conquest L3.720.4.72.6?
A quality artisanal leather strap, such as those in alligator, vegetable-tanned calf, or shell cordovan, lasts an average of 4–6 years with daily wear, increasing to 8–10 years with regular care and occasional use. Longevity depends on tanning method (vegetable-tanned resists longer than synthetic), lug wear at the pins, and exposure to humidity and perspiration. An 18-month warranty covers manufacturing defects.
