Strap for Bubble 42 White MOP

The lug width of the Corum Bubble L295/03049 is exactly 22 millimetres. This non-standard measurement requires careful selection of aftermarket straps. To verify the measurement, position a digital calliper on the internal lugs of the case where the strap attaches; the distance between the two contact points corresponds to the precise width.

The choice depends on intended use and desired aesthetic profile. An alligator strap in brown or cognac amplifies the vintage character of the model; vegetable-tanned calf leather in black offers sophistication and develops natural patina over time; a NATO canvas strap provides sports versatility; an FKM rubber strap guarantees humidity resistance. We recommend consultation with a specialist craftsman to identify the pairing that reflects your personal style.

The strap is secured via spring bars positioned on the case lugs. Use a dedicated spring bar tool to gently compress the internal pin downwards, extracting the strap from the lug hole. Insert the new strap by aligning the hole with the pin and release the tool. Verify that the pin fully engages in the resting position. This operation is recommended through a professional watchmaker to prevent damage.

Yes, the L295/03049 accepts aftermarket straps with a 22-millimetre lug width. However, as 22mm is not a universal measurement like 20mm or 24mm, the selection on the general market is limited. Specialist craftsmen offer a broader range of materials and bespoke finishes for this specific measurement, ensuring superior construction quality.

A quality artisanal leather strap (alligator or vegetable-tanned calf) maintains structural integrity for 3 to 5 years with average daily use, conditioned by proper maintenance. Prolonged exposure to humidity and temperature fluctuations accelerates ageing. A rubber strap offers extended lifespan (5 to 7 years) but requires periodic cleaning. Preventive replacement is advised when surface cracks or structural deterioration in the material become evident.
