What Is a Fake Fifty Fathoms White Gold Watch?
A fake Fifty Fathoms white gold watch is a replica of Blancpain's dive model finished to imitate the 18k white gold edition instead of the steel one. The case starts as stainless steel and takes a white gold tone from rhodium plating or a PVD coating, which gives a bright silver look with a warm edge. Real 18k white gold is a solid gold alloy mixed with palladium or nickel and topped with rhodium, so the authentic piece costs five figures while the replica sells for hundreds.
White Gold vs Steel: What Changes in a Replica
Most replica Fifty Fathoms models in this category are steel watches with a cosmetic white gold finish. Two things separate them from a standard steel replica: color depth and weight. Steel sits near 7.8 g/cm3 and 18k white gold near 15 g/cm3, so a real white gold case feels about twice as heavy in the hand.
- Color: white gold reads softer and warmer, while polished steel looks colder and reflects more blue.
- Weight: gold feels dense and top-heavy, steel feels neutral.
- Markings: gold cases carry hallmarks such as 750 or Au750 plus assay stamps.
- Wear: plating can thin at the lugs and caseback, gold cannot wear off because it is solid.
How Do Replica Makers Create the White Gold Look?
Builders use three common methods, and each one ages in a different way.
- Rhodium plating: a thin layer over polished steel. It looks close to white gold at first and costs little, but it can rub through within months on a worn watch.
- PVD coating: a harder film bonded to the case. It resists scratches better than plating and keeps its tone longer, though deep gouges expose the steel below.
- Gold plating or solid gold: thicker gold plate looks rich but softens under abrasion, while a few replicas use solid 14k or 18k gold and push the price into four figures.
Dial and Bracelet Options
White gold Fifty Fathoms models pair the case with blue, black, or gray dials, and the sailcloth strap is the most common factory pairing. Top-tier replicas copy those dials well, while entry versions get the sunburst finish wrong and show flat color. White gold tone bracelets tend to show plating wear on the clasp first, so a strap version hides age better.
What to Check Before You Buy
Inspect a few points in person or through clear, high-resolution photos. A listing with only stock images tells you nothing about the actual unit.
- Caseback engraving: lettering should be crisp and centered, not shallow or double-struck.
- Plating at the lugs and crown guards: thin spots show as gray patches.
- Bezel action: the dive bezel should click through 120 positions with no wobble.
- Dial printing: text should be sharp with even spacing, and blurry fonts are a red flag.
- Weight: ask for the gram figure on a scale, since steel cases sit far below gold weight.
- Movement: check the stated caliber and whether the rotor winds in both directions.
Case Size, Movement, and Water Resistance
The modern Fifty Fathoms Automatique measures 45 mm across, and the Bathyscaphe line sits at 43 mm. A replica that lists 45 mm but measures 42 mm on a caliper is the wrong case, no matter how good the photos look.
Water resistance is where replicas fall short. The name refers to 50 fathoms, about 91 meters, and current models are rated to 300 meters under ISO 22810 dive watch criteria. Replica gaskets, crowns, and casebacks seldom seal to that standard, so treat any replica as splash-resistant at best.
Price Tiers for Replica Fifty Fathoms White Gold
Replica pricing splits into three bands, and the finish tracks the price.
- Entry (under $150): stamped cases, mineral glass, basic plating that fades fast.
- Mid (about $200 to $400): 316L steel, sapphire crystal, decent rhodium or PVD tone, Japanese or entry Swiss-style movement.
- High (about $500 and up): closer case geometry, better bracelet finishing, thicker plating, clone automatic movements.
Solid gold replicas exist but sit near $1,000 or more, and at that point the value case changes.
Frequently Asked Questions
Does a white gold replica feel like real gold?
No. A plated steel case weighs close to any other steel watch. Only a solid gold replica comes near the heft of the genuine article.
Will the white gold finish wear off?
Plating wears with time, and contact points go first: caseback, lugs, bracelet edges, and crown. PVD holds longer, and solid gold does not wear off at all.
Can a jeweler tell a fake Fifty Fathoms white gold watch from the real one?
Yes. Weight, hallmark stamps, case finish, and movement decoration give it away within minutes. Expect no resale value either, since replica resale sits near zero.
Is a replica white gold Fifty Fathoms worth buying?
It depends on your goal. If you want the look of a precious metal dive watch at a low price and accept the trade-offs, a mid-tier piece works. If you want gold, buy gold.
Care Tips to Keep the Finish Looking Right
- Rinse with fresh water after contact with salt or sweat, then dry with a soft cloth.
- Keep it away from chlorine, perfume, and household cleaners, which dull rhodium.
- Skip abrasive polishes, since they cut through the thin coating.
- Store it dry and separate from harder jewelry to reduce scratches at the lugs.
- Check the crown seal before any water contact.
