Agelocer sells two different 44mm sport automatic lines, and the model names alone don't make it obvious which is which. The Racing line — Fast & Furious, Hollow and Square — runs the automatic Cal.A5500. The Volcano line — Automatic, Carbon Fibre and Flame Orange Steel — runs the Cal.A5505. Same 44mm-class cases, very different numbers underneath. Here's what actually separates Agelocer Racing from Agelocer Volcano, using the real case sizes, weights, reserves and prices for all six in-stock models.
Agelocer Racing vs Volcano: which should you buy?
Neither line is better outright. Of the models here, Agelocer Racing (Cal.A5500, 40–42-hour reserve, $299–$339) is lighter and cheaper on calfskin or rubber. Agelocer Volcano (Cal.A5505, 80-hour reserve, $339–$659) weighs more in steel but holds power roughly twice as long. Buy Racing for value and lightness, Volcano for the longer reserve.
Verdict: if you don't need the extra reserve, Racing is the lighter, cheaper buy; step up to Volcano only if an 80-hour reserve genuinely matters to how you wear a watch.
Best value: Agelocer Racing Hollow — $299, Cal.A5500, 123g on French calfskin.
Best on a steel bracelet: Agelocer Volcano Flame Orange Steel — $369, stainless steel bracelet, 80-hour Cal.A5505, 136g.
Best 80-hour reserve: Agelocer Volcano Automatic — $339, Cal.A5505, the same price as Racing's top Fast & Furious variant.
Best lightweight Volcano: Agelocer Volcano Carbon Fibre — $439, 120g, lighter than either steel Volcano build.
Honest flag: wearing length tops out at 230mm on the Racing models here and 220mm on the Volcano models — check your wrist size before buying either.
Racing vs Volcano: full spec comparison
| Model | Movement | Case size | Key figures | Price | Who it suits |
|---|---|---|---|---|---|
| Racing Fast & Furious Automatic | Cal.A5500 | 44.5mm / 12mm | 117g, 40h reserve, 21,600vph | $299–$339 | Fast & Furious caseback, lightest Racing |
| Racing Hollow | Cal.A5500 | 44mm / 12mm | 123g, 42h reserve, 28 jewels | $299 | Skeleton dial, calfskin only |
| Racing Square | Cal.A5500 | 44mm / 12mm | 123g, 42h reserve, 28 jewels | $299–$329 | Octagonal square case; four Steel colourways at $329 |
| Volcano Automatic | Cal.A5505 | 44.3mm / 12.5mm | 136g, 80h reserve, 28,800vph | $339 | Double the reserve at Racing's top price |
| Volcano Carbon Fibre | Cal.A5505 | 44.3mm / thickness not listed | 120g, 80h reserve, 35 jewels | $439 | 80h reserve without steel's weight |
| Volcano Flame Orange Steel | Cal.A5505 | 44.3mm / 12.5mm | 136g, 80h reserve, steel bracelet | $369 | Bracelet plus the longer reserve |
Every figure above comes from each product's own listing; the Racing jewel counts are read from the engraved casebacks in Agelocer's photos. Note that Racing isn't one spec across the board: Fast & Furious is the lighter, slightly larger-diameter build at 117g and 44.5mm, while Hollow and Square list identical specs: 44mm, 12mm thick and 123g.
Where does the real price jump sit? Not at entry level: the $339 Volcano Automatic costs the same as Racing's top Fast & Furious variant and just $40 more than Racing's $299 floor. The jump comes with case material — $439 for the Volcano Carbon Fibre and $659 for the Volcano Crystal Case.
What is the difference between the Agelocer Cal.A5500 and Cal.A5505?
Cal.A5500 (fitted to all three Racing watches here) runs at 21,600 vibrations per hour on the Fast & Furious variant, with a brand-stated 40- to 42-hour reserve. Cal.A5505 (all three Volcano watches) runs faster, at 28,800 vph, and stores roughly double the power: 80 hours. Both are brand-stated automatics; Agelocer doesn't publish independent accuracy data for either.

Jewel counts differ as well: Racing Hollow and Racing Square casebacks are engraved with 28 jewels, while Agelocer's own movement photos put 35 jewels in the Cal.A5505 across all three Volcano models here. The casebacks differ too — Volcano's photos show an exhibition window over the rotor, while Racing Hollow and Square specify a solid "etched and embossed steel bottom cover" instead. Whether either calibre is genuinely built in-house or on a modified base is a question Agelocer's own materials don't fully resolve; we cover that brand-wide in our Agelocer movements by model guide and our Agelocer brand review.
How big is the Agelocer Volcano?
All three Volcano models here measure 44.3mm across on a 24mm strap; the steel Volcano Automatic and Flame Orange Steel are 12.5mm thick, while Agelocer lists no thickness for the Carbon Fibre. That's fractionally smaller in diameter than Racing's Fast & Furious (44.5mm) but half a millimetre thicker than any Racing model (12mm). Weight is where Volcano separates itself, running from 120g in carbon fibre to 136g in steel.
Agelocer Volcano Automatic, $339 — 44.3mm, 12.5mm thick, 136g.
Is the Agelocer Racing watch heavy?
No — Racing is the lighter of the two lines. Racing Fast & Furious weighs 117g on rubber; Racing Hollow and Racing Square weigh 123g on calfskin. Both figures sit under the Volcano Automatic and Flame Orange Steel's 136g; only Fast & Furious also undercuts the Volcano Carbon Fibre's 120g, while Hollow and Square are 3g heavier than it.

How long does the Agelocer Volcano's power reserve actually last?
Agelocer states 80 hours across all three Volcano models here — Automatic, Carbon Fibre and Flame Orange Steel — at 28,800 vph. Fully wound and left off the wrist Friday evening, it should still be running Monday morning — 80 hours is just over three days. Racing's Cal.A5500 states 40 to 42 hours, so it needs winding or wearing roughly every day and a half.
Which has more case options: Racing or Volcano?
Volcano. Beyond the steel case on the Volcano Automatic and the steel bracelet on Flame Orange Steel, Agelocer also builds the Volcano Carbon Fibre at 120g and a separate Volcano Crystal Case at $659. Racing, across Fast & Furious, Hollow and Square, stays in 316L steel throughout, varying colourway and strap (rubber on Fast & Furious, French calfskin on Hollow and Square) instead of case material.
Agelocer markets that fourth case as "high-tech crystal" rather than sapphire, so don't read it as a sapphire case. For the full breakdown of all four Volcano cases, see our Agelocer Volcano review; for how the Fast & Furious co-branding sits within the wider Racing range, see our Agelocer x Fast & Furious guide.
Agelocer Volcano Carbon Fibre, $439 — 120g, the lightest of the three Volcano builds here.
Agelocer Racing Square, from $299 — the 44mm 316L steel case on French calfskin, with Steel colourways at $329.
Which Agelocer sport watch suits a big wrist?
Check the strap limit, not just the case: Racing's Fast & Furious, Hollow and Square are all rated to a 230mm wearing length. Agelocer's three Volcano models here top out at 220mm. Case diameters are close enough — 44mm to 44.5mm — that the strap's upper limit, not the dial, decides whether either line fits a larger wrist.
If you've already sized a Racing or a Volcano and want to compare them against Agelocer's other series, Racing Hollow vs Racing Square goes deeper on that pair specifically, and the full catalogue sits in the Agelocer collection.
Who should buy the Agelocer Racing, and who should buy the Agelocer Volcano?
Buy Racing if you want a $299–$339 automatic under 125g, rarely leave it off the wrist for more than about a day and a half, and like the Fast & Furious co-branded caseback or Square's octagonal case. Buy Volcano if an 80-hour reserve matters, you're fine with 120–136g, and you want a choice of rubber ($339), a steel bracelet ($369) or a carbon fibre case ($439).
Skip Racing if you often take the watch off for more than a day and a half at a time — you'll come back to a stopped watch and have to reset the time. Skip Volcano if 136g on the wrist feels like too much, unless you go for the 120g Carbon Fibre instead.
Agelocer Volcano Flame Orange Steel, $369 — steel bracelet, 80-hour Cal.A5505, 136g.
