The Big Crown 01 594 7680 4031-07 8 14 30, seen from the bench

The Oris Big Crown 01 594 7680 4031-07 8 14 30 is a 29mm stainless steel pilot's watch from the Swiss manufacturer's aviator collection, featuring the reliable Oris 594 automatic movement with hours, minutes, seconds and date display. The oversized crown, characteristic of the Big Crown series heritage from the 1940s, is paired with distinctive 14mm lugs that reflect the watch's compact proportions. The brushed and polished stainless steel case features a honeycomb bezel that reproduces vintage flight panel details, with applied indices ensuring legibility in low-light conditions.

Frequently asked questions

What is the lug width of the Oris Big Crown 01 594 7680 4031-07 8 14 30?

The lug width is exactly 14mm, a rare and specific dimension for this model. It is measured between the two inner pins where the strap attaches. Always verify with a digital calliper before ordering an aftermarket strap.

Which strap do you recommend for the Oris Big Crown 01 594 7680 4031-07 8 14 30?

Alligator leather or vegetable-tanned calf leather straps are the most refined choice, emphasising the heritage character. For a sportier look, a NATO in cotton or linen preserves the aviator spirit. A rubber or elastomer strap is ideal for dynamic daily wear.

How do you change the strap on this Oris watch?

Use a spring bar tool to push inward on the elastic pins at the strap ends. The strap detaches from the two pins (one on each side). Insert the new strap by aligning its holes with the pins and press until they click into place. Do not force to avoid damaging the lugs.

Are there aftermarket straps compatible with the Oris Big Crown 01 594 7680 4031-07 8 14 30?

Yes. All 14mm lug width straps are compatible. Milano Straps offers a dedicated collection of 14mm straps in various finishes: leather, NATO, rubber—all handcrafted and ready to ship. Visit the dedicated page to view options.

How long does a leather strap last on this watch?

A quality leather strap with proper vegetable tanning typically lasts 4–6 years with daily wear, depending on climate, perspiration, and maintenance. Regular cleaning and drying after water exposure significantly extend lifespan. Natural patina increases aesthetic appeal over time.
