Strap for Conquest Heritage Power Reserve 38 Stainless Steel / Black

The L1.648.4.52.2 features a lug width of 19 millimetres. This dimension, though uncommon in contemporary horological offerings, is characteristic of this 38mm model and requires specifically compatible straps. Accurate measurement of the distance between lugs is essential to ensure a perfect fit without lateral slippage or forcing.

The optimal choice depends on intended use and aesthetic sensibility. For timeless elegance, we recommend cognac brown or black alligator, which dialogues perfectly with the steel case and 38mm diameter. For daily practicality, Italian calf with vegetable tanning develops natural patina over time. To emphasise the sporty heritage, FKM rubber in dark blue or black offers durability and aeronautical authenticity. Shell cordovan represents the choice for those seeking unparalleled lustre and tactile quality, though it requires conscious maintenance.

The procedure requires extraction of the lateral spring bars connecting the lugs to the case. Use a dedicated spring bar tool: insert the pointed tip into the small hole on the lug, lift slightly until the bar emerges, then extract completely. Repeat on the opposite side. To install the new strap, position one spring bar into the strap's lug, approach the case, guide the bar into the case hole and press until it clicks into place. Verify both bars are fully inserted.

Yes, provided the strap is specifically dimensioned for 19mm lug width. Many quality aftermarket straps, in alligator, calf or FKM rubber, are available in this specification and guarantee complete compatibility. However, construction quality varies: prefer craftspeople who understand the specifics of the 38mm diameter and steel case, avoiding generic productions that disregard aesthetic proportions.

Longevity depends on material and maintenance. A quality alligator or calf strap, worn daily, maintains structure and aesthetics for 4–6 years. Shell cordovan, owing to its superior density, can endure 8–10 years. Vegetable-tanned leather develops fascinating patina over time, becoming softer and more characterful. Protection from prolonged moisture, excessive perspiration and direct UV rays significantly extends durability. An FKM rubber strap, by comparison, maintains elastic properties for 6–8 years of continuous wear.
