Strap for Bellflower Caree Yellow Gold / MOP / Bracelet

The lug width of the Tissot Bellflower T73.3.329.76 is 18mm. This dimension was calculated by Tissot to maintain harmonious proportions of the compact 12mm case. The measurement must be taken on the inner width of the original lug bar, excluding the lugs that anchor the strap to the case.

The best strap depends on usage context and aesthetic preference. For a classical approach, we recommend alligator with vegetable tanning or smooth calf leather in burgundy or cognac tones, which enhance the iridescence of the mother-of-pearl dial. For those seeking versatility, a technical rubber strap offers quick-change functionality and contemporary elegance without compromising the watch's sophistication.

To change the strap, remove the watch from your wrist and place the case on a flat surface. Using a spring bar tool, insert the curved tip under the lug tang to lift it slightly, then extract the metal pin (spring bar) from its housing. Repeat on the other side. Next, align the new 18mm strap to the lug openings and reinsert the spring bar, verifying mechanical lock-up.

Any strap with an 18mm lug width is compatible with the Bellflower T73.3.329.76, provided the material thickness does not exceed 3-4mm. Many Seiko, Citizen, and Mondaine models use the same standard. Always verify compatibility through direct measurements of the lug housing before purchase.

Longevity depends on leather quality and intensity of use. A vegetable-tanned calf strap typically lasts 3-5 years with daily wear. Alligator leather, due to its natural strength, can last 5-8 years. Technical rubber straps maintain functionality for 4-6 years before showing age signs. Regular maintenance—cleaning and conditioning—significantly extends lifespan.
