Search "Agelocer Tourbillon Skeleton" and you land in a pile of marketplace listings that reuse the same title across different sellers, different prices and sometimes different references entirely. We stock four distinct Agelocer skeleton tourbillons, all built on the same Cal.9001 movement, and the real decision isn't which one is "genuine" — it's leather or steel bracelet, and which case tone. Here's what actually separates the four.
Verdict: all four Agelocer skeleton tourbillons run the same 40mm, 9.7mm-thick case and the same hand-wound Cal.9001 with an 80-hour reserve. The real choices are strap (leather vs steel bracelet), case tone (rose gold vs silver), a black or blue colourway, and whether a Zircon variant is worth $200 more.
Lightest, from $799: Free-Sprung Manual Flying Tourbillon, $799 (silver or rose-gold tone) or Manual Free-Sprung Tourbillon Skeleton, from $799 (rose gold only, with a $999 Zircon option) — both 63.5g on leather.
If you want a bracelet: Free-Sprung Tourbillon Skeleton Gold Steel or Silver Steel, from $829 — 132g on a 316L chain, identical specs; pick by case tone.
Skip it if you want an automatic movement or water resistance beyond 50m (5ATM): all four are hand-wound, all four stop at 50m, and none lists an accuracy figure.
Which Agelocer Tourbillon Skeleton should you buy?
Buy the Manual Free-Sprung Tourbillon Skeleton ($799–$999) or Free-Sprung Manual Flying Tourbillon ($799) for the lightest watch, 63.5g on leather. Step up to the Gold Steel or Silver Steel version ($829–$1,029) for a bracelet. All four share the same 40mm case, Cal.9001 movement and 80-hour reserve.

Agelocer's product photography labels the Cal.9001 a 25-jewel movement, and the Manual Free-Sprung Tourbillon Skeleton's listing calls it in-house — both brand-stated, not independently verified. The two words in these names, plainly: a tourbillon puts the balance and escapement in a rotating cage, which Agelocer says offsets the effect of gravity on timekeeping. In watchmaking, 'flying' means that cage is held from one side with no bridge over the top. Only the Free-Sprung Manual Flying Tourbillon carries the word in its name, but all four list the same Cal.9001, and none of the listings documents a construction difference between them. 'Free-sprung' describes the balance: there is no regulator arm clamping the hairspring to speed the watch up or slow it down. The rate is adjusted at the balance wheel itself, which leaves the hairspring free to move. Agelocer says this adds lasting stability. For the mechanism behind the free-sprung part of that name, see our plain-English guide to what a free-sprung balance actually does; for our earlier, deeper look at an Agelocer flying tourbillon, read our Agelocer Free-Sprung Flying Tourbillon review.
Is the Agelocer Tourbillon Skeleton worth it?
Yes, if you want a hand-wound tourbillon with a skeleton dial and an 80-hour reserve at $799–$1,029, depending on strap and finish. The trade-offs: no published accuracy figures, a modest 50m (5ATM) water-resistance rating, and four closely related SKUs that take some sorting before you pick the right strap and case finish.
The open-worked dial is the point: the tourbillon cage and the movement's bridges show through the open dial, and each listing's photography shows the movement from behind through an exhibition caseback. That buys you a genuine mechanical display, not a printed dial — the same trade most skeleton buyers make, which we cover generally in what a skeleton watch is. What you don't get, on any of the four, is a stated accuracy figure in seconds per day, or water resistance beyond 50m (5ATM) — the only rating Agelocer lists, so read what a 5 ATM rating actually covers before you take one near water.
Leather vs steel bracelet: which Agelocer Tourbillon Skeleton fits how you wear a watch?
The leather versions (Manual Free-Sprung Tourbillon Skeleton and Free-Sprung Manual Flying Tourbillon) weigh 63.5g and start at $799. The steel-bracelet versions (Gold Steel and Silver Steel) weigh 132g — more than double — and start at $829. More weight means more wrist presence but less all-day comfort for a thin dress case.
Both leather models use a 20mm cowhide strap on a pin buckle, with a stated wearing length of 150–220mm. Both bracelet models use a 20mm 316L stainless steel chain closed with a butterfly buckle, and a slightly narrower stated range of 150–210mm — worth checking against your own wrist before you order either. If you specifically want a tourbillon on a metal bracelet and are open to other Agelocer references too, our roundup of tourbillon watches on a steel bracelet under $1,500 covers more options beyond these two.

Gold or silver steel — which Agelocer Tourbillon Skeleton case tone should you pick?
On the bracelet, it's the Gold Steel ($829–$1,029) for a warmer rose-gold-toned case or the Silver Steel ($829–$1,029) for a cooler finish — identical specs otherwise. On leather, the Free-Sprung Manual Flying Tourbillon ($799) is the only skeleton here offered in both silver and rose-gold tones, without a zircon upgrade.
The Manual Free-Sprung Tourbillon Skeleton comes only in rose gold, in black or blue, but adds a Zircon-finish upgrade at $999 that the Flying Tourbillon doesn't offer. The Gold Steel and Silver Steel bracelets each carry their own Zircon-finish upgrade at $1,029. In every case the Zircon variant costs $200 more than the standard finish in that same model, and nothing else in the spec sheet changes.
The Free-Sprung Tourbillon Skeleton Silver Steel, from $829 — same case and movement as the Gold Steel, cooler tone.
Is the Agelocer Tourbillon Skeleton automatic or manual wind?
Manual wind — every Agelocer Tourbillon Skeleton here is hand-wound, not automatic, whatever a marketplace listing title says. All four list the same Cal.9001 movement running at 28,800 vph (4Hz) with an 80-hour power reserve, roughly 3.3 days. Nothing winds it as you wear it, so you top it up by hand.
That means you wind it by hand, and a watch left in a drawer over a long weekend will still be running when you pick it back up — a real practical upside over a shorter-reserve watch. For winding technique, our guide on how to wind and set a tourbillon watch without damaging it covers the technique properly rather than us trying to summarize crown positions here.

How thick is the Agelocer Tourbillon Skeleton?
Every model here measures 9.7mm thick in a 40mm, 316L stainless steel case — under 10mm despite the tourbillon, and the same whichever strap or finish you choose. Choosing the bracelet adds weight (132g vs 63.5g on leather), not thickness.
If case thickness specifically — rather than the leather-vs-steel or color decision — is what's driving your search, our roundup of thin tourbillon watches from $799 covers other slim tourbillon options. For general background on what a tourbillon cage actually does inside any watch, our plain-English tourbillon explainer covers the mechanism itself.
When should you skip the Agelocer Tourbillon Skeleton?
Skip it if you need an automatic (all four are hand-wound), water resistance beyond 50m/5ATM (the rating all four share), or a published accuracy figure — none of the four listings states one. Also skip the Zircon colorways if $200 more than the standard finish isn't worth it to you.
If you'd rather read a wider, brand-level verdict before committing to the skeleton line specifically, our honest look at Agelocer as a brand is the place to start. Otherwise, the full Agelocer collection has all four of these in stock, with worldwide shipping and buyer protection on every order — pick leather or bracelet, pick a tone and colourway, and the listed 40mm case, Cal.9001 movement and 80-hour reserve are the same across all four.
