Very nice and friendly. Try the best to assist their customers.

Alican Ş.

This is my 5th purchase from Crono24 and Twain time is the best seller until now. You can shop here they are experts. I shopped during pandemic and everything went much better then my expectations They shipped from NY to Dubai and even did the service I requested. The results are fantastic Thank you ”Ornella” for all the support I am very happy with my new vintage AP Rolay Oak 👏🏻👏🏻👏🏻👏🏻👏🏻

Patrick K.

I recently purchased a watch using Chrono24 from the dealer Twain Time out of New York and my experience was beyond compare. The level of communication exceeded my expectations and the quality of the watch I received was better than pictured. Ornella was on top of the transaction and was truly concerned with my level of satisfaction. I would extraordinarily recommend this high-end jeweler.

Roger B.

Absolute pleasure to do business with. Very helpful and accommodating. Highly recommended!

Kent Murphy

Joshua

Excellent service and response time. Trustworthy and diligent.

Kathryn Robbins

Exceptional service! I am so happy with my purchase. Because of the pandemic I had to rely on photos rather than visiting in person. In every way Twain Time exceeded my expectations. I highly recommend them.

Daniel Lee

I just wanted to highlight their commitment to customer service, even during these pandemic times. My entire experience was terrific - from start to finish. They are incredibly knowledgeable and really want to understand what the client wants, never pushing the sale. Regarding the condition of my watch - I was very happy to see that the watch came in impeccable condition, even better than the description on their website. I dealt directly with Ornella and found her very helpful and caring as well. I bought my watch through the phone and she took care of me during the entire process. Highly, highly recommend Twain Time.

Erik Barrios

I came across Twain Time's Instagram account and saw that they were listing a watch I had been looking for. They were very responsive to inquiries and readily provided additional information about the piece (including condition, service history, additional pictures, etc.). When I received the watch, the condition was as good as described and they encouraged me to contact them if there were any issues after the fact. I would happily deal with them again.

Patrick Koballa

I recently purchased a watch online from Twain Time and my experience was perfect. The level of communication exceeded my expectations and the quality of the watch I received was better than pictured. Ornella was on top of the transaction and was truly concerned with my level of satisfaction. I would highly recommend this high end jeweler.
