Italian elegance in every detail.
This GENUINE ALLIGATOR LEATHER STRAP, handcrafted in Italy by master artisans from the Marche and Veneto regions, represents the true essence of ColaReb luxury.
The semi-gloss finish and tone-on-tone stitching enhance the natural texture of this precious leather — soft to the touch and capable of giving any timepiece a distinctive character. The hypoallergenic lining ensures maximum comfort, even with daily use.
Perfect for prestigious watches such as Cartier, Vacheron Constantin or Jaeger-LeCoultre, this strap is designed for those who recognise the difference between an ordinary accessory and an authentic Italian creation.
Choosing ColaReb means embracing the tradition of Made in Italy, where time is synonymous with beauty, care, and artisanal mastery.
Each strap is unique; the photo represents the size, model, and colour. Variations in texture from one strap to another confirm the authenticity of the leather.

FAQ
Which length is right for me?
It is designed for wrists of about 17 to 21 cm in circumference: the size of the watch case matters too. On the same wrist, a 44 mm case needs a shorter strap than a 38 mm one. If in doubt, our size calculator will help you find the right fit.
Are spring bars included?
Yes, quick release spring bars: you can change the strap in seconds, without tools.
How do I care for it?
Avoid contact with water. No creams or conditioners are needed: the leather is already treated and finished with special fats and oils that are best left untouched.
Are the marks on the leather defects?
No. Differences in texture are typical of genuine alligator leather and confirm its authenticity.
Available lengths and sizes
To find the best strap for your watch and your wrist, you first need to know the different lengths and sizes available. Follow the steps below:
1. Width of the lug
To know the width of the lug pin of your watch, measure with a ruler the distance between the two lugs, the protruding ends in the upper and lower part of the watch to which the strap is attached.

2. Lenght of the strap
For optimal use of the watch, it is essential to purchase a strap of a length suitable for your wrist. Measure the length of the last strap that felt comfortable.
3. Size of the buckle
All our straps are supplied with a stainless steel buckle, normal or satin finished depending on the model, on which the ColaReb® logo is engraved. If you wish to use the buckle of a previous strap, for example, the one supplied with the watch, compare the size of your buckle with the one in the descriptions of our products.
4. Thickness of the strap
From an aesthetic point of view, thin or flat watches are better matched to thin straps, while robust and large watches require a thicker strap for better ergonomics and a more homogeneous design.
