What is Calibre 333116?

Calibre 333116 is a factory label used on some Chinese-made replica Rolex movements, not an official Rolex calibre number. It shows up mainly on replica Day-Date and Datejust builds that imitate the Rolex 3255 and 3235. The string is a catalog code from the replica supply chain, so two watches sold as 333116 can contain different movements.

Is Calibre 333116 a real Rolex movement?

No. Rolex publishes its own calibre references, and 333116 is not among them. Genuine Rolex calibres use four-digit numbers such as 3135, 3235 and 3255. The six-digit 333116 format matches the internal part-numbering style used by replica parts dealers.

What movement is usually inside a 333116 replica?

Most watches sold under this label carry a Chinese automatic movement built to copy the geometry of a Swiss design. Common bases are ETA 2824 and 2836 clones made by Seagull, Hangzhou and Dixmont Guangzhou. Factories then add engraved bridges, a decorated rotor and a Rolex-style oscillating weight so the movement resembles a 3235 or 3255.

Beat rate and power reserve

Better 333116 movements run at 28,800 vibrations per hour, the same 4 Hz rate as the ETA 2824-2 they copy. Power reserve is usually 38 to 42 hours. A watch ticking at 21,600 vph is a lower grade build, not the version normally advertised.

Date, winding and setting

Most 333116 builds use a quickset date at the crown rather than the instantaneous date change of a real 3235. Hacking is standard, so the seconds hand stops when the crown is pulled out. The crown usually has two positions: winding, then time and date setting.

How do you check a 333116 movement?

• Ask for a photo of the movement with the caseback removed, not a catalog render.
• Measure the beat rate with a timegrapher or a watchmaker app; 28,800 vph confirms the advertised clone.
• Look for engraved rather than printed lettering, which signals a higher grade of decoration.
• Confirm the rotor spins freely and that the watch winds in both directions.

What problems do owners report?

Rough winding feel and noisy rotors are the most frequent complaints. Grit left inside the movement at the factory causes premature wear, so a cleaning and re-oiling at a local watchmaker is worth the cost. Water resistance is rarely pressure tested and should be treated as splash protection only.

Can a 333116 movement be serviced?

Many independent watchmakers will service an ETA-clone movement but refuse to work around heavily decorated bridges. Replacement parts stay cheap and are ordered under the base movement number, not under 333116. Note the base reference before booking any repair.

What does a 333116 replica cost?

Entry builds often sell for under 150 USD and use a basic 21,600 vph movement. Mid tier builds with a decorated 28,800 vph clone run roughly 250 to 450 USD. Top tier builds with a Swiss ETA base cost more and are the only versions worth servicing long term.

Legal and practical notes

Replica watches are counterfeit goods, and importing or selling one can lead to seizure at customs in the United States. Resale value is effectively zero, and no factory warranty applies. Treat any 333116 listing as an unregulated product sold without recourse.
