Strap for Conquest 34 Stainless Steel - Pink Gold / Purple / Bracelet

The lug width of the Longines Conquest L3.430.5.98.6 is 17 millimetres. This is the distance between the two spring bars of the case. It is a non-standard measurement compared to current catalogues, requiring straps specifically manufactured for this exact width.

For a rose gold and stainless steel two-tone case, alligator leather in a dark cognac brown is the most balanced choice. Alternatively, glossy shell cordovan dialogues elegantly with the steel, whilst vegetable-tanned calf develops patina gradually over time.

To change the strap, you will need a dedicated spring bar removal tool. Measure the width between the spring bars (17mm for this model) and the length from the bar to each case extremity. Gently remove the bars, extract the previous strap and insert the new one, ensuring the bars seat completely in both lugs of the case.

Yes, provided it is specifically manufactured for 17mm lug width and crafted by specialised artisans. A high-quality aftermarket strap—in alligator, shell cordovan or calf—offers greater personalisation than original straps, with options for colour, closure and custom finishing.

A high-quality leather strap (alligatore, shell cordovan, vegetable-tanned calf) typically lasts 5–8 years with regular daily use. Longevity depends on care, sun exposure and humidity. The patina that develops is an indicator of authenticity and correct material ageing.
