Guide to Your Choice
To find the best ColaReb strap for your watch and your wrist, you need to know the different lengths and sizes available. Follow the steps below:
Lug Width
To determine the width of the lugs of your watch, use a metric ruler to measure the distance between the two lugs (the protruding ends to which the strap is attached).

Strap Length
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.

Buckle Size
All ColaReb straps are supplied with a stainless steel buckle (polished or satin-finished depending on the model), on which the ColaReb logo is engraved. If you want to use the buckle from a previous strap (for example, the one supplied with the watch), compare the size of your buckle with the one in the product description.

Strap Thickness
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.

Replacing the Strap
To remove the old strap from the lugs of your watch and install the new one, follow the steps below:
The strap is usually attached to the watch with spring bars. Use a spring bar tool to locate the end of the spring bar between the strap and the case.

Then, push in the end of the bar to extract it from the hole in the case and remove the first side of the strap. Perform the same operation on both sides.

Replacing the Buckle
To remove the buckle, use a spring bar tool as you would for the strap. Place the tool between the buckle and the strap on one side, and push the end of the spring bar towards the center.

Remove the spring bar using the spring bar tool.

Lug/Buckle Taper Many straps taper in width toward the buckle. This is an important measurement if you plan to swap out the buckle or add a deployant clasp. Your buckle size matches the width at the BUCKLE end of the strap, not the lug end.

I have a few colareb straps I really like them. Of course they cost little more but O prefer to spend double but to enjoy a quality look and feel since day one. If you think and compere to other 100 or 200 straps 60 70 is not much more specially if you love your watch.
Bought this to replace a scratched-up metal band on a Shinola Canfield, and am very happy with it! It complements the watch well and the leather is clearly good quality (I'm a sucker for the new-leather smell too). Looking forward to having the band break in over time, and it should last for many years. I've bought other bands from Holben's before, and am always happy with their quality and prompt shipping.
