Top-tier service. They gave a super fair trade value on my 2024 DJ, and got me a 2007, MINT condition submariner. I couldn't be happier. 1-day shipping, incredible communication. Please don't hesitate to work with TNS.

TNS Diamonds and Watches exceeded all my expectations! Their customer service was truly outstanding—friendly, knowledgeable, and attentive throughout the entire process. The pricing was clear and straightforward, which made the experience even better. They set excellent expectations and delivered on every promise. Within 5 minutes of paying for my timepiece I had my tracking information. I’m thrilled with my purchase and can confidently say this is my go-to place for timepieces. I’ll definitely be coming back for my text timepiece. Merry Christmas!!

I had an amazing experience working with Austin at TNS Diamonds! He helped me source a watch I’ve always wanted that’s been out of circulation, and he found it within a week in perfect condition. The entire transaction was seamless, and Austin was a pleasure to work with—knowledgeable, professional, and never pushy. If you’re looking for expertise and excellent service, I highly recommend TNS Diamonds!

My wrist was naked for 6 months. I needed a daily to wear. I had previous experiences with Austin so I decided to visit the newly renovated store. Told Austin exactly what I wanted and he serviced me as if I was a purchasing a high end time piece. His priority was customer satisfaction! I got my daily with a great price, thank you Austin!Francois

I have been following Austin’s videos for a long time and have learned a ton about watches and the industry from him. When he put up a Tag Heuer Carrera watch on a video I felt this was a chance to actually buy something from him. After texting and a quick phone call at 4PM I had a beautiful watch delivered to me and on my wrist the next day. The entire process was a pleasure.
Meliton Otero

If you are looking for a smooth, safe and flawless purchase look no further. TNS has helped me secure multiple watches, done seamless trades and is exactly what you look for when making a purchase for a watch on the secondary market. Truly professional in every aspect of the transaction. The true demonstration of a business’s quality is their repeat customers. I can attest that after a few purchases, I plan to come back for my future watch purchases.

Austin and his team made my watch buying process a delight. They are so knowledgeable about every brand/model of watch, and are very patient in answering any questions. They are absolutely fair in their pricing, and are open to non-traditional deals. Watch their videos online if you want to learn about watches, and also want to become more knowledgeable about how individual brands work and how the industry works. They can be trusted 100% to be fair and transparent with you when you work with them!

Great experience with TNS in purchasing a used Submariner. Had watched Austin on Insta and built trust. Dealt with Jay via phone and text. They sent good pics and video (in addition to the pics on the website listing) and answered my questions. Negotiated fairly and delivered a great watch as listed and described on the phone. Very pleased and would definitely do business with them again.
Chris Crocco

Thanks Austin and the whole team at TNS! Excellent experience from first contact through completion of the transaction. I was super excited to be finally getting a Rolex Daytona and to be able to work a trade for some other watches that were of value to them and achieve my grail watch was awesome.

Purchasing my Rolex Yacht-Master from TNS was easy and a great experience. I asked them for detailed pictures, a video and more information, all of which was provided quickly. I was able to negotiate with them for an incredible price and the watch arrived quickly in better shape than described/expected. Austin was very helpful and personable, no chat bots here! I will definitely be checking their website for more deals in the future and reaching out to purchase my next watch hopefully soon.

I have nothing but good to say about my experience with TNS Diamonds and Austin. Austin made the process incredibly smooth and pleasant.

Great people to work with !I had a couple watches that weren't getting the love they deserved , so , after following TNS channel on Instagram and watched their content on TikTok, I decided to send them a message requesting a trade deal towards another piece , they were pretty straight forward, they provided me with a shipping label for my watches and after a couple days I had my new watch delivered overnight to me .Would definitely work with them again !

I had been searching for the right Rolex Sub for a few weeks. And I happened upon this account on TikTok and really enjoyed their content. I ended up buying a Sub from them and it was a great experience. The watch arrived 1 day after I purchased it. Packaging was perfect and the watch was in great shape. I will be buying from them again. Highly recommend.

I had a very good experience buying a Ulysse Nardin GMT from Austin. They actually had two in stock. They sent me high quality photos that allowed me to select the one I preferred. Fast responses and fair pricing helped make the deal.
Prasana Devanand

This was my first time buying from Austin at TNS. I reached out on IG in response to a unique new watch he had posted (GP Arabic Laureato). Austin was quick to respond to all my questions, and was also willing to video call me to walk through the watch short after. He was very professional through the process, and seemed like he genuinely enjoyed interacting with me. His pricing was very fair based on online comps, and we sealed the deal within minutes of me reaching out. Austin seems to genuinely take an interest in his clients and he very knowledgeable about his products. I would happily recommend TNS to any potential customers, and look forward to working with Austin again.

I recently purchased a Christopher Ward C1 Bel Canto from TNS after seeing their videos on social media. Every step of the process was smooth and enjoyable. They sourced the watch due to not having it in stock and did so very quickly. Additionally, the price was more than fair. You don’t have to worry about the authenticity of the watch as their standard process is to inspect every watch thoroughly before sending out. I highly recommend working with TNS and they have gotten a repeat customer in myself now.
Herb Schulze

TNS Diamonds is top-notch! I first found Austin and TNS Diamonds on Tiktok and Instagram and was immediately impressed with how they do business. I finally pulled the trigger and reached out to them about a Rolex watch that I have always wanted. They did not have it in stock at the time, but Austin was able to source it for me in less than a week! I received my watch yesterday and I could not be any happier. He made sure I get a genuine watch and walked me throughout the process. What’s more impressive is that all communication was just through text messaging and e-mail. Don’t hesitate to do business with these guys. Will definitely work with them again in the future! Thank you and more power!
