What a replica Luminor Due 48mm is

A replica Luminor Due 48mm is a 48mm-wide Panerai-style watch. It copies the Luminor Due shape: cushion case, crown guard, sandwich dial, and thin profile. Panerai lists Luminor Due cases at 38mm, 42mm, and 45mm. A 48mm version is not in the current Panerai catalog. Sellers use the 48mm size because it matches the Luminor Marina 1950 case. Buyers who want a large Panerai look pick 48mm.

Case and size

48mm across, 13mm to 14mm thick. Lug width 24mm or 26mm. Weight 110g to 140g with a steel case. 316L stainless steel is the common material. Sellers list titanium. Titanium versions weigh about 30% less. The crown guard is the lever-lock type on Luminor models. Luminor Due models use a thinner crown guard. Check photos: the lever should sit flush and lock with a small click.

Movement

Most 48mm replicas use a Chinese automatic movement. Common calibers: Seagull ST25, Hangzhou 6300, or a decorated 21-jewel copy. Power reserve 36 to 42 hours. Beat rate 21,600 vph or 28,800 vph. Genuine Luminor Due uses a P.900 or P.9010 movement. Those run at 28,800 vph with a 3-day reserve. A replica will not match that. Ask the seller for a movement photo. Look for a rotor with engravings and a balance wheel.

Dial and hands

Sandwich dial: two plates, cutouts for numerals and markers. Lume is applied between the plates. Replica lume is weaker than genuine Super-LumiNova. Hands are pencil or baton style. Small seconds at 9 o'clock is standard. Date window at 3 o'clock on some models. The font on the dial should match Panerai's: "LUMINOR DUE" and "PANERAI" in caps. Spacing matters. Ask for a straight-on photo.

Crystal and case back

Sapphire crystal with anti-reflective coating. Some low-cost replicas use mineral glass. Test with a water drop: sapphire beads, mineral spreads. The case back is solid on Luminor Due. Some replicas use a display back. Genuine Luminor Due has a solid back with engravings. Check the engraving depth and font.

Water resistance

Replica sellers claim 50m or 100m. Do not trust that. Gaskets may be missing or poor. Genuine Luminor Due is rated to 30m or 50m. A replica can leak in rain. Keep it away from water unless a watchmaker tests it.

What to check before you buy

  • Ask for real photos, not stock images.
  • Ask for a video of the seconds hand sweeping.
  • Check the crown guard lever action.
  • Confirm lug width (24mm or 26mm) for strap changes.
  • Ask about shipping method and customs risk.
  • Price range: $150 to $500. Higher price does not always mean better quality.

Legal note (US)

US Customs and Border Protection can seize replica watches. Selling a replica as genuine is trademark counterfeiting. Penalties can reach $2 million and 10 years for a first offense. Personal imports can be seized. This is a fact, not legal advice.
