Why synthetic rubies are inside your automatic
If you’ve been researching watch jewels, you’ve probably noticed that quality varies wildly across the market. At DR.WATCH, we’ve built our reputation on bridging the gap between cost-prohibitive Swiss originals and the watches our customers actually wear day-to-day.
This post breaks down the details that matter — the movement, the steel, the finishing — and offers practical guidance whether you’re a seasoned collector or buying your first premium timepiece. Feel free to 15-day returns as you read.
Inside the Movement
The heart of any serious watch is its movement. Low-end replicas run Chinese quartz modules — they keep time, but they tell you nothing about horology. DR.WATCH superclones use Swiss-grade automatic movements that operate on the same principles as the originals: a mainspring wound by an oscillating rotor, a balance wheel beating at 28,800 vibrations per hour, and a power reserve typically between 38 and 70 hours depending on the caliber.
What does this mean in practice? The sweep of the second hand is smooth, not ticking. The watch winds itself as you wear it. If you set it aside for a weekend, it’s still running on Monday. And the service intervals — unlike cheap replicas — are measured in years, not months.
- Swiss-grade automatic movement (clone of original caliber)
- 28,800 vph (4Hz) beat rate for smooth sweep
- 38-70 hour power reserve depending on model
- Hand-adjusted for +/- 10 seconds daily accuracy
Materials That Define the watch jewels
The materials in a luxury watch are where the real price difference becomes meaningful. Cheaper replicas use 316L steel — perfectly fine for everyday objects but noticeably different in hand from 904L, the alloy Rolex pioneered for their Oyster cases. 904L resists corrosion, holds polish longer, and has a distinct cool, dense feel that collectors recognize immediately.
Beyond steel, the crystal matters. Mineral glass scratches. Hardened mineral glass still scratches. Only sapphire — rated 9 on the Mohs hardness scale — will keep looking new after years of daily wear. Every DR.WATCH superclone uses genuine sapphire crystal with anti-reflective coating, bonded by the same processes used in authorized service centers.

- Ceramic bezel inserts on applicable models
- Super-LumiNova or equivalent luminescent material

Final Thoughts
