I have a TAG watch I love that I bought twenty-five years ago. It sat in a drawer after the band broke, became stagnant, and needed a lot of work. TNS not only brought it back to life, but it looks and feels better than when I first got it. Definitely check this place out. They know their stuff.

Phenomenal experience! I reached out to TNS for a Rolex Pepsi even though it wasn't listed on the website. Austin was able to quickly track one down at a fair price. I used several watches and a little cash to get the deal done. He offered amazing trade-in value which allowed me to finally obtain my grail! I highly recommend Austin and TNS for the value they provide their customers which was evident by the deal he made with me. I will definitely keep them in mind the next time and you should too.

Austin found my dream timepiece for me. He tracked down two options and guided me through which would be best. Dealing with Austin on this watch is the best online retail experience I have ever had. This is my second purchase from him and the first was perfect. He is always in your corner and ensures that you get exactly what you are looking for. I will never buy a watch from anyone else. JG

It was a professional, responsive, and knowledgeable experience all around. I purchased a watch from them recently, and they got all the details right. I highly recommend them.

I just received my watch and its as nice as Austin said it was. They provided a great response when communicating by email and even provided me a video of the watch so that I could see it since I am out of state. After dealing with 2 different AD's locally for the past 3 years and getting nowhere this was a welcome change. I would highly recommend them for your next watch or jewelry purchase.

I have now bought and sold several watches with Austin at TNS. I have other dealers that I work with, but he is the best. And not just on the transaction but has been responsive on questions I have had that are about watches in general. I have learned a lot from him and consider him at the highest level in terms of ethics and customer service. You will not be disappointed in any way working with him. I have already referred two friends that have had a similar experience.

I had a watch I wanted to sell and a watch I wanted to purchase. Austin was great with quick responses and made the transactions seemless. I received the watch and was extremely satisfied. I normally only purchase through AD, but this company is reasonable and provided exceptional quality items and service. I highly recommend and will be a repeat customer.

Purchased a watch from TNS this week and the service and shipping were first rate! As to the actual watch, it exceeds expectation. For all intents and purposes the watch, while pre owned, appears brand new. In addition, the price was excellent. Will definitely be doing future business with TNS.

A huge fan of the TikTok account. They are well informed, genuine, and inspire trust. After months of following them and their inventory, I finally saw a neo vintage time piece I liked. It shipped to Los Angeles quickly and was delivered as advertised. Can’t wait for my next purchase! Thank you!

I wanted to give TNS and Austin a shoutout for their honesty and service. I reached out to them on eBay and made the process of a watch deal super easy and worth while. Austin knew what I wanted after speaking with me and he wasn’t pushy at all. For anyone looking for a watch or a trade deal, don’t look any further and reach out to TNS. Austins goal is to make you happy with your purchase. I couldn’t be any happier. I will go back to Austin and tell anyone that likes or knows about watches to reach out to him. He will give you his number and communicate with you without leaving you hanging for days. Don’t look any further!

I drove from Harrisburg to meet a friend and shop for a Cartier Roadster watch. We stopped into TNS and found a couple that I really liked. There was absolutely no pressure to buy what so ever. We got a price and said we would be back. After we walked around for about an hour I realized no one could come anywhere near the price we were quoted. I went back and purchased the Cartier. As we were checking out we got to see a really cool FP Journe and hung out talking watches. I really enjoyed my time at TNS and feel like I’ve found my new watch dealer!

I sold two watches from Omaha, Nebraska and the process was great. I sent in the photos , we agreed on a price , I shipped out the watches , and got paid when they arrived instantly .I would 100% suggest working with TNS if you are selling or buying a luxury watch .

I have been looking for an upgrade from my citizens and seikos and met Austin the owner. The shop specializes in higher end pieces but he was able to find me this amazing Omega Constellation and through wonderful communication with Jay we settled on a price that was very fair and within my budget. Love the piece and the experience was top notch! Don’t waste your “time” with anyone other than TNS!

I recently purchased my first Rolex from them, and when Austin pulled out the watch, I was blown away. It looked even better than the pictures online, and I knew right away that I had to have it. TNS knows how to find watches in insanely good condition, and they are also super duper nice people!
Tim Lee

Great experience dealing with Austin at TNS Diamonds. First time buying an expensive item online so I was worried about such a large wire transfer but everything went smoothly and professionally. Austin is a busy person but still took the time to answer my questions and sent me the watch on a Sat! Watch was delivered professionally packaged and just as described. Definitely recommend purchasing jewelry from a local small business like TNS Diamonds.
