You don’t see this variant too often—and honestly, it kind of surprised me how much I liked it. Tantalum case, rose gold details, and a 40mm size that just wears really well. It’s not the loudest AP, but under $10K, this feels like a sleeper win.

This client paid $19.5K for a Rolex Kermit that’s now worth $9.5K—bought from an AD’s pre-owned section.
We helped him offload it and score a stunning AP Code 11.59 at $21K off retail.

TNS Diamonds & Watches
136 South 8th Street, Philadelphia
- I’ve been following TNS on social media now for a while. The educational and watch authentication videos made me feel comfortable purchasing from them. Saw a watch that I liked and within 2 days I had it. Came just as advertised and the … More customer service was great. Will definitely be back for more watches. Appreciate all the help and I love my watch.
- I had been eyeing this Panerai for about a year. Would occasionally check prices on Chrono24 when I came across this listing from TNS Diamonds. Had never heard of them but after reading a bunch of reviews and watching their videos online … More I went ahead and took a chance. We'll I'm glad I did as the watch came in exactly as described, maybe even slightly better than their description. I couldn't be happier with their service. Placed the order Thursday night from Texas, received an email the following day with a tracking number and package was delivered on the following Tuesday. I truly believe TNS Diamonds care about their customers. Don't hesitate to deal with them!!
- I wanted to personally give a shout out & 5 star review to Arielle at TNS Diamonds. My husband lost his grandfather's ring, which was incredibly sentimental to him. Arielle helped us recreate this ring! We sent her a photo of the … More ring & she supplied cad drawings of the ring with options of different carat gold & Diamond choices, which best represented the original. It looks AMAZING! She knocked it out of the park & we couldn't be happier with the results!
- Excellent experience trading in and purchasing a new watch with Austin. Highest caliber customer experience. Will definitely be purchasing through TNS in the future!
