I came to this workshop to have my MoonSwatch customised. The work on the watch is excellent, and the team is attentive and professional. This is exactly the kind of watchmaking workshop we love. I will definitely come back for another project or purchase. Many thanks to Noah. I highly recommend this workshop. 👍🏽

Thank you, Noah, for your professionalism, kindness, the way you treat your customers, myself included, and your exceptional after-sales service. Once you come to your workshop, you never want to go anywhere else. I found you by chance while looking for a real watchmaker. What a lucky coincidence!! CCA

I wanted a unique watch, something a little different from what you usually find in stores. After watching a few of Noah's videos on social media, I took the plunge. My first impression of the boutique said it all: a small workshop that radiates professionalism, with one beautiful watch after another. Talking to Noah quickly put all my doubts to rest. He is genuinely passionate! We designed the watch I had imagined together, and his valuable advice helped me refine my choices. Because of the colours I chose, especially for the strap, some parts had to be ordered, yet my watch was ready in just 15 days. The result is stunning, the watch feels high quality and the packaging has a luxury feel. A thousand thanks! This is my first order and certainly not my last. See you soon.

Stumbled across the shop when I did a google search of nearby watch stores as I knew I wanted to get a watch while visiting Paris. Noah and the other technician were so pleasant to deal with no pressure at all as I looked and looked at all the models. Was happy to put a different bracelet on a watch I was considering and answered all my questions. Extremely knowledgeable. When I finally picked my watch he was a perfectionist in making sure the clasp was perfectly positioned (I was fine with it being slightly off but not Noah). I do not speak French but my wife who is fluent noticed how helpful he was when someone phoned the shop with a question.

I am posting this review after wearing my 36 mm Explorer for several months. I am very satisfied with the watch and Noah's work. I am very particular about accuracy, and the movement performs well, gaining only a few seconds a day. The watch is beautifully made, and the micro-adjustment clasp is a real advantage. I also had occasion to use the after-sales service for a small adjustment. Communication with Noah was incredibly smooth, and shipping the watch back and forth was trouble-free. Being able to speak directly to the watchmaker who designs and builds your watch is a major plus! In my opinion, the value for money is unbeatable. I am a demanding buyer and will undoubtedly come back to Noah for another timepiece. Thank you, Noah, and keep up the great work.

I am still amazed at how incredible this watch is! The quality is simply impressive, with care given to every detail… It is genuinely top-level work. Honestly, it is so beautiful I almost hesitate to wear it for fear of damaging it. It looks like a collector's piece. I am completely won over — love at first sight ❤️ Thank you to the team at Atelier N.A Timekeeping.

I have always loved watches and was very glad I entrusted my project to Noah Assouline. Quite frankly, this is the best workshop I know for creating a watch that meets your expectations. I wanted a Bettarini (Panerai) style case in a more discreet 40 mm size. I received it today and it is BEAUTIFUL 🤩

I collected my watch today and had it engraved on site. Noah Assouline is fantastic. You can tell how passionate he is. Thank you for his advice — I am very happy with my “orange” purchase. Bruno des Mouettes.

I bought a Seiko Batman in December, ordered it online and picked it up in the boutique. Noah was extremely responsive to messages, offered excellent advice and was very professional. He is also very friendly, and I had the pleasure of meeting him at his shop. I am really pleased with my watch, its quality and the whole experience. I wholeheartedly recommend him and will definitely do it again. There is also an absolutely stunning tourbillon watch in the boutique!
