Not a great experience unfortunately

If I could give no stars I would. I’m out money and my product.
Placed an order for my husband for Christmas. I ordered the wrong width and asked for an exchange. I returned per their rules and in a prompt manner. Two weeks later I had to check in only for them to tell me there was a strong odor on the straps. I find this bogus and he even admitted it was in someone else mailbox. The straps didn’t fit therefore were never tried on or out of original packaging and we shipped a few days after Christmas so they were not just laying around.
I can no longer get a response or even a refund since January 14th hence my honest review. I will be filing a claim I guess since I can’t get a response and now have no product after PAYING to send it back. :( Unfortunate because if this was handled appropriately we would’ve been good customers and sent our friends their way as well.
Adding our email exchange for proof.

Hi Jessica,

Thanks for your candid review. I apologize for the frustrating experience. We always want happy customers.

As noted in my email, our return policy clearly states that 'All product packaging (bags, tags, cases, etc.) must be unaltered. Items that have been worn, resized, damaged or otherwise modified (including exposure to cologne, smoke or other odors) will not be accepted for return or exchange.'

I was able to get the scent out of the Bonetto Cinturini strap in order to sell it as used through our Holben's Attic store. I'll keep the ColaReb strap for myself to use in the future on a watch because of the scent. Though it represents a loss for us as a small company, I am sending your replacement straps today.

As a family business we try our best, and have done so for close to twenty-five years. We have an excellent reputation for customer service. We've processed hundreds of returns without issue, and have thousands of satisfied customers who have been working with us for years. I am sorry if you felt that my last email to you sounded bogus, as it was not - I hate having to write such emails and fortunately haven't had to for some time now. I hope your husband enjoys the straps on his TUDOR watch.

Best regards,


Kevin E.
Cinturini 300D Black Rubber Strap

I’m super pleased with my purchase and love the deployment clasp! I put this on a Citizen Promaster Dive watch and it pairs up well with the watch. Just take your time when sizing which was very easy but you don’t want to cut it too short! I would recommend it to anyone looking at this style strap.

Bonetto Cinturini 300D Black Double Face Rubber Watch Strap

Bonetto Cinturini 300D Black Double Face Rubber Watch Strap. Great strap for my Resco Patriot. Customer service is flat out awesome. You have a question the answer super fast

Very Happy All Round

I was never comfortable with the original rubber buckle strap on my superOcean... it felt either too tight or too loose and was emblazoned with Breitling all over it which I always found unsettling!
After plenty of research I ordered the Bonetto Cinturini 300D and have been REALLY IMPRESSED - so much more comfortable, with the ability to make fine adjustments to the make it the perfect fit.
It LOOKS AMAZING - really high quality and my kids love the faint vanilla scent! The buckle is very secure with both chrome finish and brushed alloy which matches the watch case perfectly.
It's so good - I'm now tempted to buy another orange strap for the summer hols!
Though they are manufactured in Italy, this particular strap is unavailable in the UK. It took around 2 weeks to arrive in the UK from USA which was as expected.

This is a good quality rubber strap that smells like vanilla. It is difficult to cut straight but can be filed down to straighten. I am using this on a Seiko samurai. The samurai uses fat spring pins and this strap does not. I am looking for spring pins to fit the samurai holes. Too bad Holben’s doesn’t sell them.
