Short answer
Rolex does not publish a caliber numbered 14250. The string works as a vendor code in replica listings, not as a Rolex movement name. Sellers use it for a Chinese-made automatic movement, a 25-jewel design running at 28,800 vibrations per hour (4 Hz) in most cases. The label alone proves nothing. You have to open the caseback.
Rolex 14250 Bracelet and Case Replica Quality
Listings use 14250 with no fixed meaning. Two sellers can attach the same number to different movements. Rolex reference numbers in the 14xxx range exist, for example 14233 and 14270, so the string may also be a case reference used as a movement label.

What buyers look for
People searching this term want three facts: which movement sits inside, how it performs, and whether the label is honest.
- Movement family: Chinese automatic, 21,600 or 28,800 vph
- Jewel count: 21 to 25, sometimes overstated
- Power reserve: 36 to 42 hours for this class
- Date change: slow creep or instant flip at midnight
How to check the movement
- Remove the caseback with a wrench or rubber ball.
- Photograph the movement plate. Look for engraved caliber numbers, jewel count, and maker marks.
- Run it on a timegrapher. 28,800 vph reads as 8 beats per second.
- Check amplitude. 250 to 310 degrees is normal for a healthy movement.
- Wind it 40 turns, set it down, and time how long it runs.
- Watch the date window between 23:50 and 00:10.
Movement classes seen in replicas
Chinese 2813: 21,600 vph, 21 jewels, low cost. Clone ETA 2824 or 2836: 28,800 vph, 25 jewels. Clone 3135: 28,800 vph, 31 jewels, decorative finishing. Genuine ETA 2824-2: 28,800 vph, 25 jewels, about 38 hours of reserve. A real Rolex movement comes from Rolex service or the used market. Rolex does not sell movements to third parties.
What "Swiss movement" means in a listing
Swiss Made requires 60% of production costs in Switzerland. The movement must be Swiss, the watch cased in Switzerland, and the final check done there. A movement alone does not make a watch Swiss Made. Some listings use "Swiss" for a Chinese movement with a Swiss-made rotor or a Swiss ebauche assembled elsewhere.
Price context
A basic Chinese automatic movement sells wholesale for tens of dollars. A genuine ETA 2824-2 costs over $200 from a parts supplier. Replica listings use movement names as a price lever, so the label carries a premium.
Practical takeaway
Treat 14250 as a seller code. Ask for a movement photo, a timegrapher reading, and a power reserve number. If a seller cannot supply those three items, the number carries no weight. Repair paths differ: a clone 3135 needs a watchmaker with clone parts on hand, while a 2813 is replaced instead of serviced.
