Answer

A replica Luminor 1950 8 Days copies Panerai's PAM00233 and related references. The original uses a P.2002 hand-wound movement with a 192-hour power reserve. Most replicas use a 21-jewel Asian movement. The power reserve is often decorative. Case size is 44 mm. Water resistance is 30 m to 50 m on most replicas, not 100 m.

Original specs

Panerai released the Luminor 1950 8 Days GMT as PAM00233. The case is 44 mm. It uses AISI 316L steel. The crystal is sapphire. The movement is P.2002. It has 21 jewels. It runs at 28,800 vph. It has twin barrels. The power reserve is 8 days. Functions include hours, minutes, small seconds, date, GMT, 24-hour indicator, and power reserve indicator. Water resistance is 100 m.

Replica movement types

Replica makers use several movements. One common type is an Asian 6497 hand-wound movement. Another is an Asian automatic with a GMT module. A few high-end replicas use a decorated hand-wound movement. A true 8-day reserve is rare. Test the reserve by winding the watch to full wind. Let it run. Note the stop time. A real 8-day movement runs 192 hours. A replica often stops after 36 to 48 hours.

Case and dial checks

Check the crown guard. The lever must lock. The crown must sit flush. Check the lugs. They should be 24 mm. Check the crystal. Sapphire reflects light with high contrast. Mineral glass shows more scratches. Check the dial text. The print should not blur. The date window should align. The GMT hand should move in 24-hour steps. The power reserve indicator should move when you wind the crown.

Price ranges

Low-grade replicas sell for $80 to $150. Mid-grade replicas sell for $200 to $400. High-grade replicas sell for $500 to $900. These prices vary by movement, case finish, and dial print. Original PAM00233 prices on the secondary market range from $6,000 to $10,000. Condition, box, and papers change the price.
