Macro view of a mechanical watch movement showing gears and jeweled bearings

The Greubel Forsey Tourbillon 24 Seconds Vision costs roughly a quarter of a million dollars. At that price, and with that name on the dial, you might expect more to be going on when you look at it from the front. Then you turn it over and find a sapphire bubble rising off the back […]

The Watch Dealer Behind Your Local Jeweler

Team photo of the staff. A diverse group of smiling employees in a modern office setting.

Some of the biggest watch dealers in the country are companies you’ve never heard of. They’ve never posted a video, and they almost never sell to a consumer directly. Their entire business runs through relationships with hundreds of traditional jewelry stores. In our world, that’s what a watch dealer for jewelry stores looks like. When […]

We Just Got In This Million-Dollar Voutilainen, and the Internet’s a Powerful Place

Close up of the exposed mechanical movement on the back of a Voutilainen watch, resting on a cloth with its brown leather strap visible.

Let me just tell you how this thing ended up in our hands. A couple weeks ago we posted a video about a Voutilainen we bought and sold, and it got a decent amount of views. Other collectors who own Voutilainens saw it, and some of them reached out. I was able to secure another […]

How Watch Consignment Works at TNS Diamonds

Wooden watch box with divided compartments holding several luxury watches including a Shinola, illustrating a watch consignment service.

What Consignment Actually Means Here When we consign a watch, we’re not buying it off you. You still own it. We authenticate it, photograph it, price it, list it, and negotiate with buyers on your behalf, and you get paid once it sells.   People assume consignment and trade-in are the same conversation. They’re not. […]

The Krayon Anyday and Why Serious Collectors Are Going Independent

Krayon Anyday luxury watch shown front and back, featuring a perpetual calendar dial and exposed rose gold movement

When Austin posted about the Krayon Anyday, the comments section filled up with people who had never heard of the brand asking what they were looking at. That reaction — the pause, the second look, the genuine curiosity from people who thought they knew the watch world — is exactly what independent watchmaking does when […]

From Rolex to Cartier to AP — The Watches That Actually Move

Pre-owned Rolex Submariner steel watch resting on a pink surface, shown as the fastest-selling used luxury watch

In the pre-owned luxury watch market, not everything sells the same way. Some references move within hours of being listed. Others sit for weeks regardless of how competitive the price is. The difference rarely comes down to quality alone. It comes down to demand depth — how many buyers are actively looking for that specific […]

What to Expect When You Sell or Trade a Luxury Watch

Most people who walk into TNS Diamonds to sell or trade a watch have never done it before. They know what they paid, they have a rough sense of what it’s worth, and they have questions they’re not always sure how to ask. The process is more straightforward than most people expect, but it helps […]

Audemars Piguet Royal Oak chronograph with a blue dial, octagonal steel bezel, and gold screws, displayed on a white cushion in dramatic ambient lighting.

The Audemars Piguet Royal Oak is one of the few watches in the secondary market that commands genuine six-figure prices in steel. That kind of value creates an obvious counterfeiting incentive, and the replica market for the Royal Oak has become increasingly sophisticated over the past several years. Super-clones that once failed on obvious details […]

How Social Media Is Changing the Landscape of Luxury Jewelry Buying

Social media luxury jewelry buying has gone from a niche phenomenon to a mainstream force reshaping the entire market. Reddit threads move price comps in real time. YouTube educators are creating informed buyers overnight. Instagram accelerates trend cycles that used to take years. The result: buyers arrive differently than they ever have before.   That […]
