Agelocer Model Numbers Explained: 9001, 9101, 9201 and 6411

Search for "Agelocer 9101" or "Agelocer 6411" and you'll land on marketplace listings, a competition entry, or a forum thread — most of them quoting the bare reference number, none of them telling you which series that number actually belongs to. If you've seen a code like 9001A1, 9204S11 or 6411A7 and want to know what watch it is before you buy, this Agelocer model number decoder matches it, using the exact references in our own catalog.

Quick decoder table: reference, series, calibre, case, strap width

What does an Agelocer model number actually tell you?

An Agelocer model number pairs a four-digit series code with a letter-and-number suffix. In our catalog's references, the digits identify the watch family and dial color (9001 black, 9004 blue; 6411 grey, 6415 green), and the suffix identifies the version: case tone, zircon, bracelet or transparent case. For example, 9204S11 is the blue Sapphire Skeleton tourbillon.

The suffix names the version: on the Free-Sprung Flying Tourbillon, A1 is steel, D2 rose gold, and E1 and F2 the zircon versions; the Rainbow Bezel uses K10R/L10R, the transparent-case tourbillons use S, and the Astronomer has its own suffix set. Because 9101 and 9104 each appear on two different watches, always read the suffix.

That's the gap this page fills. Competition entries and secondhand listings often quote the full code — something like 9204S11 or 6411A7. Shops selling it new tend to use the series name instead ("Sapphire Skeleton", "Astronomer Moonphase"). Neither side cross-references the other, so a shopper who only has the number is stuck.

What is the Agelocer 9001 (and 9004)?

9001 and 9004 are the two dial colors of Agelocer's Free-Sprung Flying Tourbillon: 9001 is black, 9004 is blue. Both run the hand-wound Cal.9001 at 80 hours' reserve in a 40mm, 9.7mm-thick steel case on a 20mm strap, priced at $799 for the four standard finishes and $999 for the four zircon versions.

It's the lowest-priced tourbillon on this page, and the series name alone ("Free-Sprung Flying Tourbillon") doesn't tell a buyer which of the eight color options they're looking at. The suffix does: A1 is steel, D2 rose gold, E1 steel with zircon, F2 rose gold with zircon. The Free-Sprung Flying Tourbillon product page lists all eight: Blue Silver, Silver Black, Black Rose Gold and Blue Rose Gold at $799, plus the same four finishes with zircon stones at $999.

What is the difference between the Agelocer 9101 and 9104?

9101 is the black version and 9104 the blue version, but the same pair of numbers appears on two different Agelocer watches, so read the suffix. K10R or L10R means the Tourbillon Rainbow Bezel Ceramic: 42mm listed dial diameter, steel case, zirconia ceramic bezel, $1,099. An S suffix (9101S11, 9104S1) means the Ice Never Melts Crystal Tourbillon at $1,299.

The Tourbillon Rainbow Bezel Ceramic listing covers four colorways: White Blue Rose Gold, White Black Rose Gold, Deep Sea Blue and Obsidian Black. The bezel itself is zirconia ceramic, not a gem-set ring, which is worth knowing if a listing's photos make it look like stones. The watch weighs 93 g and water resistance is rated to 50m (5 ATM). Unlike the other three tourbillon references here, this listing doesn't publish a separate calibre code — only the shared 80-hour reserve and 28,800 vph frequency.

What is the Agelocer 9201 / 9204?

9201 and 9204 are the two colorways of the Tourbillon Limited Edition Sapphire Skeleton: 9201 is Gem Black, 9204 is Sapphire Blue. Both use a genuine sapphire-glass case, 40×42mm and 11mm thick, on an 18mm silicone strap with a folding buckle, at $1,899 — the only sapphire case among the references in this guide.

That last point matters for anyone comparing this to the Ice Never Melts below: of the tourbillon references covered on this page, only the Tourbillon Limited Edition Sapphire Skeleton lists sapphire glass as the case material itself. One thing to note: the watch listing gives an 18mm strap width, while the original replacement strap for 9201/9204 is listed at 26mm, so order a spare strap by reference number rather than by measuring. At 85 g it's lighter than the 93 g Rainbow Bezel despite the 11mm-thick sapphire case.

What does the "S" in 9101S mean?

In our catalog, S marks a transparent-case tourbillon. 9101S and 9104S are the Ice Never Melts Crystal Tourbillon in AGELOCER high-tech crystal; 9201S11 and 9204S11 are the Sapphire Skeleton in sapphire glass. The steel-cased Rainbow Bezel versions of 9101/9104 carry K10R or L10R instead, and the digits after S (S1, S10, S11) identify the individual variant.

The Ice Never Melts Crystal Tourbillon runs the hand-wound Cal.A9001 in a 42.5mm, 11.8mm-thick case, on a 22mm silicon rubber strap, at $1,299 — $200 more than the steel-cased 9101/9104 and $600 less than the sapphire-cased 9201/9204. It comes in six variants: black or blue movement on silicone, black or blue movement on white rubber, black movement on black rubber, and black movement with white adhesive tape. It's a limited edition, so check the product page for current stock before committing to a specific variant. For the full breakdown of this watch, see our Ice Never Melts review.

What's the difference between the Agelocer 6411, 6412 and 6415?

6411, 6412 and 6415 are dial colors on the Astronomer 29.5-Day Moonphase: 6411 is grey, 6412 is black or brown, and 6415 is green. All three share the 40mm steel case, Cal.A4610 automatic movement and 20mm strap, at $499 on leather or $529 on a steel bracelet.

This is the one series here that isn't a tourbillon — it's an automatic watch with a moonphase complication, which is why the calibre and price sit well below the 9001/9101/9201 family. Across the images on the Astronomer 29.5-Day Moonphase listing you'll also see codes like 6411A9 or 6415D9 — in our catalog images a trailing 9 marks the steel-bracelet versions, and 6411D7, 6411D9, 6415D5 and 6415D9 are the rose-gold-tone grey and green variants. Not every letter maps cleanly, though: 6412D2 is simply the brown-dial version, so match the code to the photo rather than assume. Agelocer markets the moonphase disc as accurate to a 29.5-day cycle; treat that as a brand claim rather than an independently measured one, and see our full Astronomer review for more on what that claim does and doesn't tell you.

Which original strap fits your Agelocer reference number?

Match the reference to its strap width: 9001/9004 take the 20mm original strap in leather or steel; 9201/9204 take the 26mm clear silicone strap; 6411/6412/6415 take the 20mm Astronomer strap in leather or steel; 9101S/9104S take Agelocer's own rubber strap for the Ice Never Melts case. The Rainbow Bezel versions (K10R/L10R) aren't covered by these straps; that listing specifies 22mm fluorine rubber.

The Agelocer Original 20mm Replacement Strap for Free-Sprung Tourbillon (9001/9004) is $85 in silver steel, rose gold steel, black leather or brown leather, sized for a 150–220mm wrist. The Agelocer Original 26mm Clear Silicone Strap for Sapphire Tourbillon (9201/9204) is also $85, translucent silicone with a 316L steel buckle for a 170–230mm wrist. For 6411/6412/6415, the Agelocer Original 20mm Replacement Strap for Astronomer 29.5-Day Moonphase comes in grey, black or brown leather, or silver or rose gold steel, at $85. And for the Ice Never Melts case (9101S/9104S), the matching part is the Agelocer Original Rubber Replacement Strap for Ice Never Melts Tourbillon (9101S/9104S), also $85, in white, black or clear. Each is listed as the original Agelocer part for the references named in its title, which is the main reason to buy the matching part rather than a universal strap — especially for 9201/9204, where the watch listing and the strap listing give different widths.

How do you find the reference number on your watch or in a listing?

Our product listings don't document where the reference is printed on the watch, so the fastest way to confirm it is to match what you can see — dial color, case size, case material and strap width — against the decoder table above, rather than relying on a listing's series name alone.

This is exactly the gap that marketplace listings and competition entries leave open: a single-reference page won't show you the sibling references, and a marketplace title often names only the complication ("tourbillon", "skeleton") without the code or the price. If you've got a number and a photo, work through the table top to bottom — case material and strap width narrow it quickly, but watch the overlaps: the Free-Sprung Flying Tourbillon and the Astronomer are both 40mm on 20mm straps (one is a hand-wound tourbillon, the other an automatic moonphase), and the Rainbow Bezel and Ice Never Melts both take 22mm straps (steel case with a rainbow bezel versus a transparent crystal case). If you've got a watch in hand with no listing at all, the same matching exercise works in reverse: measure the case and strap, check the dial color, and read off the reference.

Buying the one you decoded

Once you've matched your number to a product, buying from PrimeTimepiece's Agelocer collection gets you the in-stock variant, worldwide shipping and buyer protection on the order — rather than a thinly described secondhand listing with no way to confirm the strap, case material or current price. If what you actually need is a replacement band rather than a whole watch, the full range sits in Watch Straps, and for a deeper look at what's running inside each of these references, our Agelocer movements by model guide covers the calibre side in full.
