Quartz vs Mechanical Accuracy Race – Watch Drift Race Simulator
Two rate tiers start together. Over a simulated year compressed into seconds, you watch the accuracy gap become visible.
Last updated: 20 Aug 2026 · Educational simulation using common accuracy tiers, not a certificate test.
Sample result (works without JavaScript):
A typical mechanical watch at +10 s/day can be thousands of seconds off after a year, while many quartz watches stay far tighter over the same period.

How to read the race
- Position shows accumulated time error over the simulated period
- Farther along the track = more absolute drift in this model
- Quartz usually accumulates less error per day than common mechanical rates
- COSC-level mechanical can still lose a long race to ordinary quartz
Accuracy specs feel abstract until a year is compressed into seconds.
Educational model only. Real watches vary with temperature, position, magnetism and service state.
Frequently Asked Questions
Is quartz more accurate than mechanical? Usually yes at typical consumer tiers.
What is COSC in s/day? About -4 to +6 s/day under test conditions.
Real physical test? No — sped-up educational simulation.
