Strap for Chronofighter Oversize

The Graham Chronofighter 2CCAU.B09A features a lug width of 24mm. This measurement refers to the perpendicular distance between the lateral pins of the case, not the visual width of the mounted strap. To verify correctly, use a calliper positioned at the base of the attachments and measure the clear space. Never confuse lug width with the mounted strap width, which will always be slightly smaller.

We recommend alligator leather of superior quality with vegetable tanning for the 2CCAU.B09A, as it creates a natural aesthetic dialogue with the ceramic and carbon case. The natural pattern of alligator scales respects the technical sophistication of the G1747 movement. Alternatively, high-quality calf leather with vegetable tanning or shell cordovan offer predictable ageing and distributed patina. For operational use, NATO webbing or vulcanised rubber guarantee superior resistance to extreme conditions.

Strap changing requires removal of the pins connecting the strap to the lugs. Equip yourself with a spring bar tool and position it in the small lateral groove of each pin. Push upward with steady pressure to compress the internal spring and disengage the pin from the lug. Once extracted, the old strap separates easily. Insert the new strap by aligning the attachments with the lugs and reintroduce the pin using the same lever action, verifying the lock. Avoid abrupt movements during the operation.

Yes, any strap with the correct 24mm lug width is compatible with the 2CCAU.B09A, regardless of the manufacturer. Compatibility depends exclusively on pin geometry and lug width, not on the watch brand. We recommend verifying that the strap is manufactured to precise tolerances and that the pin holes are correctly centred. An artisanal strap of superior quality guarantees enhanced comfort and durability over time.

The lifespan of a leather strap depends on the material and conditions of use. High-quality alligator or calf leather with vegetable tanning typically lasts 5-8 years with moderate daily wear. Frequent exposure to perspiration, water or sunlight reduces durability. Natural leather continues to age and develop patina even after decades, but may require specific treatments after 3-4 years to maintain elasticity. A vulcanised rubber strap offers superior durability (10-15 years) with minimal maintenance, making it ideal for Chronofighter watches destined for tactical use.
