Frequently asked questions

What is the lug width of the JeanRichard Terrascope 60520-11-601-FB6A?

The JeanRichard Terrascope 60520-11-601-FB6A features a lug width of 24mm. This measurement is critical for selecting the correct strap: always ensure you order a 24mm strap and do not confuse it with standard 20mm or 22mm sizes. The 24mm lug width is proportioned to the 44mm case and guarantees a balanced passant without wobbling.

Which type of strap is most suitable for the JeanRichard Terrascope 60520-11-601-FB6A?

Three approaches are recommended for the Terrascope. For elegance: an alligator in tobacco tones with pronounced grain creates a compelling contrast with the steel case. For conscious ageing: vegetable-tanned calf develops a rich patina over time. For intensive outdoor use: a NATO strap in heavy canvas or FKM rubber ensures minimal maintenance and outstanding water resistance. Your choice depends on intended use and your appreciation for material evolution.

How do you change the strap on a JeanRichard Terrascope 60520-11-601-FB6A?

Changing the strap requires few steps and a dedicated tool. Position the watch strap-side up. Insert a spring bar tool (or small tweezers) into the slot beneath the lug and press gently downward to release the internal spring mechanism. Remove the old strap from both lugs. Insert the new strap into the first lug and push the spring until you hear a click, confirming engagement. Repeat on the opposite lug. Avoid excessive force to prevent case damage.

Are aftermarket straps compatible with the JeanRichard Terrascope 60520-11-601-FB6A?

Yes, aftermarket 24mm straps are fully compatible with the Terrascope 60520-11-601-FB6A. Standard 24mm lugs accept any strap of matching width, regardless of manufacturer. Before purchase, verify that strap thickness does not exceed 3mm (otherwise the passant may bind) and confirm width is genuinely 24mm, as some brands have manufacturing tolerances of ±0.5mm. Artisanal straps of superior quality ensure a visual and tactile result far superior to generic replacements.

What is the lifespan of a leather strap on a JeanRichard Terrascope 60520-11-601-FB6A?

An artisanal-quality leather strap lasts 3–5 years of daily wear, with variation based on material and environmental conditions. Alligator, owing to its natural structure, resists wear better than ordinary calf. Vegetable-tanned calf, whilst developing a beautiful patina, remains more vulnerable to moisture and requires conscious maintenance (avoid immersion; dry after rain). FKM rubber, conversely, offers extended lifespan (5–7 years) provided regular cleaning and protection from prolonged direct sunlight.
