The Conquest V.H.P. L3.727.2.66.6 (aka: L37272666), seen from the bench

The Longines Conquest V.H.P. L3.727.2.66.6 is a quartz chronograph with a 44mm stainless steel case and 22mm lug width. Equipped with the L289.2 caliber, it delivers ±5 seconds per year precision (V.H.P. standard) and features the GPD system for automatic hand reset after impacts. The model integrates hours, minutes, small seconds at 6 o'clock, date window, and chronograph function, representing the evolution of the tool watch lineage since the late 1950s.

Frequently asked questions

What is the lug width of the Longines Conquest V.H.P. L3.727.2.66.6?

The lug width is 22mm, which corresponds to the diameter of the mounting tube between the case lugs. This dimension determines the width of the compatible strap. To verify the measurement, use a digital calliper positioned on the inner lug shoulder and measure the distance between the two attachment holes.

Which strap is most suitable for the Conquest V.H.P. L3.727.2.66.6?

For this 44mm model with tool watch character, we recommend vegetable-tanned Tuscan leather in dark brown (moro scuro) tone, which creates a sophisticated dialogue with the stainless steel case. Alternatively, genuine alligator guarantees fine fibre structure and natural water resistance, or shell cordovan for a tactile surface that evolves over time. For sport contexts, high-resistance FKM rubber or cotton-polyester NATO straps complete the options.

How do I change the strap on the Longines Conquest V.H.P. L3.727.2.66.6?

Strap change occurs through the spring bar lug system. Use a spring bar tool (strap removal tool): insert the flat tip between the lug and the lug post, apply gentle pressure inward to release the spring, then withdraw the lug from the hole. Repeat on the other side. Next, position the new strap and reinsert the spring bars, verifying attachment with a light pull.

Are Milano Straps aftermarket straps compatible with the Conquest V.H.P. L3.727.2.66.6?

Yes. Milano Straps manufactures artisanal 22mm straps customisable in length, initials and stitching thread, specifically designed for the Longines Conquest V.H.P. L3.727.2.66.6. All straps in the 22mm collection feature standard ISO attachment holes, ensuring compatibility with original lugs. Fast shipping and technical support included.

How long does a leather strap last on the Longines Conquest V.H.P. L3.727.2.66.6?

Durability depends on material and maintenance. Quality vegetable-tanned Tuscan leather maintains structural integrity for 4–6 years in daily wear, with possible restitching after 3 years. Genuine alligator may last 7–10 years if regularly dried after moisture exposure. Shell cordovan, being extremely dense vegetable leather, extends lifespan to 8–12 years. Casati Milano provides 18-month warranty and maintenance services.
