ℹ️ Volatility
Annualised price fluctuation. Below 10 % = very stable, 10–20 % = normal, above 20 % = volatile. With high volatility the price can change quickly — in both directions. Be cautious about buying without checking the current price.

ℹ️ Investment Grade A/B/C/D
ChronoCheck's own rating for each reference. A 0–100 point scale, made up of four weighted components:
- Momentum (40 pts) — trend strength from the momentum score.

- Source robustness (15 pts) — number of independent market sources.
- A · 75+ Trend is right, liquidity good, data broad.
- B · 55–74 Solid, but one component weaker.
- C · 35–54 Average, volatility or market breadth weigh on it.

IWC Ref. IW356802 — Variants and collector names
Known as: Aquatimer 2000, IWC Diver 2000, Taucher 2000
Production phases and changes
- 2009: Launch of IW356802 as part of the new 3568 Aquatimer family; switch from the internal rotating bezel (Ref. 3548) to an external unidirectional rotating bezel with sapphire crystal underside and 6-layer Super-LumiNova
- 2011: Minor revision of the bezel mechanism; bracelet version (IW3568-01/08) received a fully brushed finish
- 2013: Discontinuation of IW356802; succeeded by the new Aquatimer generation IW356810/IW356811 (external rotating bezel, Cal. 30110) as well as IW358xxx with SafeDive inner rotating bezel and in-house Cal. 80110
In 2009, IWC gave the Aquatimer family a thorough ground-up redesign. The IW356802 arrives with a black dial and rubber strap; sister reference IW356801 shares the dial but wears a steel bracelet instead. The defining feature across the entire 3568 series is an external unidirectional rotating bezel with a sapphire crystal underside and 6-layer Super-LumiNova on the minute markers. The previous generation under Ref. 3548 used an internal bezel — move to the external ring and the difference is immediately apparent the moment you operate it. Water resistance stands at 2000 meters, a specification IWC treats as a genuine commitment with this line rather than a marketing footnote.
## What the Caliber 30110 Delivers — and What It Costs to Keep Running
Beating inside the case is the Caliber 30110, built on the ETA 2892-A2 platform and fitted identically across all three 3568 variants. For buyers, that's a tangible advantage: service intervals are predictable, the movement is widely supported, and you won't find yourself hunting down a specialist watchmaker who can charge what they like for a proprietary caliber. In 2011 IWC made a minor revision to the bezel mechanism; visually the IW356802 stayed largely the same, while the bracelet variant IW356801 received a fully brushed finish at that point.
## Four Years of Production, a Clean Succession
The IW356802 ran only through 2013. At SIHH 2014, IWC restructured the entire Aquatimer lineup: the IW358xxx family arrived with the SafeDive inner rotating bezel and the in-house Caliber 80110 delivering 44 hours of power reserve — a technical step forward that moved the 3568 series straight onto the discontinued list. In the collector market the reference circulates under the names "Aquatimer 2000," "IWC Diver 2000," and "Taucher 2000." Anyone specifically after the ETA-based generation with an external bezel and none of the SafeDive overhead lands squarely here.
Brand profile: IWC
IWC Schaffhausen produces high-quality pilot and sports watches. The Portugieser, Pilot's Watch (Big Pilot + Mark XVIII/XX), and Portofino are the most frequently faked references. Since 2025, APS Factory V3 has produced integrated 52010 super-clones with correct case thickness — classic tells (case thickness, movement visibility) are only partially reliable against these. Key checks today: engraving depth, seconds tick interval, thermally blued hand color, and sub-dial proportions.
- Serial number: genuine IWC serials are 6 digits, purely numeric, on the caseback — all serial numbers are verifiable in the IWC 'My IWC' portal. Fakes often have 7 digits or a mix of letters and numbers.
- Portugieser sub-dial seconds intervals: a GENUINE piece has exactly 3 mini-ticks between each seconds index (high beat rate of 28,800 vph) — fakes have 4 or irregular ticks (lower beat rate).
- Caseback engraving 'International Watch Company': genuine engraving is DEEP (perceptible with a fingernail) and sharp-edged — fakes are shallower, sometimes just laser-printed rather than truly engraved. Test: raking light and a loupe.
- Portugieser/Portofino blue hand color: thermally blued steel shifts from deep blue to light violet depending on viewing angle — painted fake hands show a flat, uniform blue.
Serial number format: IWC serial numbers: 6-digit numeric on the caseback. Verifiable online via the IWC My IWC Portal.
