Siena features smooth vegetable-tanned calfskin with off-white stitching and oval sizing holes running through the center of the strap. The simple unpadded construction and matte finish give it a clean vintage look without heavy distressing or oversized detailing. Made in Italy.

Material & feel

The strap is made from full-grain Italian calfskin leather that has been vegetable tanned, giving it a firmer feel at first that gradually softens with wear. Hand stitching is done in an off-white thread, and the oval holes are cleanly cut. The buckle has a brushed finish. The underside is lined with calfskin leather that is breathable and hypoallergenic.

Excellent straps this is my 3rd I really like them they look better as they get older they give a nicer color and sheen. I like them so much that I give them as presents because I want other people to experience this strap :) the price to me it is a fair price considering the quality and how long last and the thickness of the soft leather.

The strap arrived in a week to New Mexico via USPS I was able to track the shipment while it was with USPS. Excellent quality leather, in the short length I prefer. I will definitely buy Colareb again and from Holben’s. I’m wearing it on my Alpinist Seiko but you can use it on a Rolex no problem is that good

Excellent

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.

Love it!

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.

Colareb siena blue watch strap is beautiful. Super soft and comfortable right out of the envelope. It really sets of my Helm Miyako blue dial watch beautifully. And as always Holben's service was outstanding, on its way within hours of placing the order.

Really Good quality it matches with my Black PVD watch. Only wish that the black buckle was the same style as the one that comes with the strap.

Beautiful strap, Excellent Customer Service

The strap arrived quickly to Canada via USPS and Canada Post and I was able to track the shipment while it was with USPS. Excellent quality leather for $60 US, in the short length I prefer. I will definitely buy Colareb again and from Holben’s. I’m wearing it on my Timex Expedition and Islander ISL-107.

Excellent Strap and Customer Service

I knew I wanted to try Colareb vintage leather straps, the price with Holben’s was as good as ordering direct from Colareb in Italy. The straps arrived quickly to Canada via USPS and Canada Post and I was able to track the shipment while it was with USPS. Excellent quality leather for $60 US, in the short length I prefer. I will definitely buy Colareb again and from Holben’s. First pic is the strap on my Long Island Watch Company 39mm Flieger ISL-107.

Great alternative

I didn’t care or the original band on my Hamilton Khaki field. This band, paired with the the black stainless buckle is a solid alternative!

Beautiful strap

The leather is super nice and love the smaller size options for small wrists, well worth the price.

Appealing to sight, touch, and smell

I knew out of the box I would want to replace my Orient Sun and Moon V3’s deployment clasp. I looked around a few places, saw the reviews on here, and picked up a set. Now it’s so much easier to put this watch on and it feels very secure in my wrist! Also, I can’t help but smell that wonderful leather scent.

Very high quality leather strap

It's a excellent upgrade from my stock watch strap. The design and construction of the strap is very well made. The strap is thick enough to hold its shape after a couple of weeks use, but very comfortable to wear, easily broken in after just a few hours on the wrist. Would definitely buy Colareb again in the future.

ColaReb Siena Strap

Love this strap! High quality leather along with great design and construction...and the great leather aroma! I replaced the regular buckle with a Hamilton deployment single fold clasp. I will probably order more for some of my other watches. One suggestion would be for the strap holes to be slightly closer together to enable better fit choices.

Top notch leather strap

Just amazing quality and best looking leather strap. Wholes can be tighter though.

Excellent leather strap with one minor negative

Excellent strap. The one thing that could be better is the spacing of the holes. They could be placed closer together for a more precise fit. Other than that I am very pleased with it. I'd by one again should I need another.

Looks, feels and smells amazing

I am absolutely in love with this strap on my Seiko Chrono. It took a regular ol' quartz watch and turned it into something that looks downright glamorous, at least to me. The quality of the leather is worlds above the Archer strap I bought before and quickly returned. I have a small wrist, but the last hole on the watch provides a perfect fit. I can't wait to see how the leather breaks in and ages over time, but even right out of the box it was soft and flexible. This is my first "nice" strap and it runs circles around the $20 ones I'm used to buying. It was a bit of a treat myself moment, but I don't regret it for a second. Only problem is now I want to buy a few more in different colors/combinations for the rest of my collection!

It is so comfortable. I like to remove those clinky old metal ...

This strap is gorgeous, thick and burly. I put it on my Orient blue dial Mako II. It is so comfortable. I like to remove those clinky old metal bracelets that come with the watches and replace 'em with these handmade leather ColaReb straps. Each strap is handmade and one of a kind. The more you wear 'em the better they look and you want to wear the heck out of 'em! They get better and better the more you wear 'em. What can I say about it except that I looooove ColaReb straps!
