Frequently asked questions
What is the lug width of the Oris Big Crown 01 594 7680 4361-07 5 14 77FC?
The lug width of the Big Crown 01 594 7680 4361-07 5 14 77FC is 14mm, a non-standard and specific measurement. This dimension is determined by the geometry of the 29mm case and requires dedicated straps. To verify the correct lug width, measure the internal distance between the two spring bar pins protruding from the sides of the case, not the external width of the case itself.
Which strap type pairs best with the Big Crown 01 594 7680 4361-07 5 14 77FC?
Vegetable-tanned alligator is the most refined and harmonious choice: its pronounced grain beautifully complements the oversized crown and stainless steel case. Chromium-tanned calfskin in brown or black offers everyday elegance and predictable ageing. To emphasise the aviatorial heritage, a robust NATO strap in fabric evokes the 1940s instrument aesthetic. FKM rubber in black represents the contemporary solution, balancing practicality, moisture resistance, and formal tone.
How do you change a strap on a 29mm watch with a 14mm lug width?
Strap replacement requires a simple tool: a spring bar tool or small flathead screwdriver. Position the watch on a soft surface with the case facing upward. Insert the tool into the small hole on the spring bar notch, compress the pin inward, and slide the old strap away from its seat. Repeat on the opposite side, then insert the new 14mm strap by seating the pins securely in their housing.
Where can I find aftermarket 14mm straps compatible with the Big Crown?
14mm straps are less common than standard widths, but available through specialist artisans such as Milano Straps, which curates a collection in leather, NATO, and FKM rubber in various colours. Engaging bespoke leather craftsmen ensures superior construction quality and noble materials. Milano Straps also offers online customisation and fast shipping worldwide.
How long does a natural leather strap last on a watch like the Big Crown?
A high-quality leather strap—alligator, chromium-tanned calfskin, or shell cordovan—typically lasts 3–5 years under daily wear, depending on ambient humidity and frequency of use. Vegetable-tanned leather ages more elegantly but requires regular air exposure and protection from prolonged moisture. Robust materials such as NATO and FKM rubber exceed 7–10 years without perceptible degradation. Periodic maintenance—air-drying after perspiration, light protective treatments—significantly extends longevity.
