ℹ️ 1-month trend
Price change over the past 30 days. Shows the short-term market movement — relevant if you want to buy or sell soon.
ℹ️ 4-month trend
The central metric behind the momentum score. It filters out short-term swings and shows the true, medium-term market trend of this reference.
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 Momentum score
ChronoCheck's own indicator from 0 to 100, calculated from the 4-month trend, volatility and market direction.
- Above 60 — Upward trend. Good time to sell, prices are rising.
- 40 – 60 — Neutral. Stable price level, no pressure to act.
- Below 40 — Downward trend. Wait or enter at a good 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.
- Liquidity (25 pts) — number of active live listings.
- Stability (20 pts) — inverse volatility — the calmer, the better.
- 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.
- D · below 35 Downward or too little data — a collector's piece.

Brand profile: Rolex
Rolex is the most counterfeited watch brand in the world. Super-clones (VSF, ARF, Clean — the latter inactive since the 07/2025 raid, with only old stock still circulating) reach 95%+ similarity. Authenticity can almost always only be identified through micro-details and caliber behavior.
- Case back: ALWAYS solid and closed — any display window means it's definitely fake (exception: vintage Ref. 6085 only)
- Minute hand length: genuine Rolex minute hands end EXACTLY at the minute chapter ring. 1 mm too long = fake. The strongest VSF tell.
- Seconds hand: smooth sweep without any hesitation — the slightest tick-tock motion means it's fake
- Cyclops lens (on Date models): must magnify exactly 2.5×, with the date filling almost the entire window
Serial number format: Since 2010, a random alphanumeric combination (e.g. 'G3M9K721'). 2000-2010: a letter plus 6-7 digits. Serial number engraved on the rehaut at 6 o'clock (from ~2005). Older models: between the lug shoulders at 6 o'clock on the case.
