Short answer

The replica Rolex 1908 ref. 52517 is a copy of Rolex's modern dress watch, the Perpetual 1908 that replaced the Cellini line in 2023. The genuine article is a 39mm platinum watch with a small seconds hand at 6 o'clock and an ice blue dial. Replica quality swings hard. Cheap versions get the silhouette and the dial layout roughly right, then fall apart on dial texture, hand finishing, and the crown profile. The better ones, usually $300 to $600, sit close enough in proportion that nobody notices on your wrist.

These are the things I check before calling any 1908 replica worth the money.

The real watch in one paragraph

Rolex built the 1908 as a proper dress piece, not a sports watch on a leather strap. It runs 39mm across, sits about 9.5mm thick, and carries the calibre 7140, an automatic movement with a 66-hour power reserve and a Superlative Chronometer rating of -2/+2 seconds a day. Water resistance is 50 metres, which is fine for hand washing and nothing else. Gold versions use an intense white dial. The platinum version gets the ice blue dial, and that colour is the single hardest thing for a replica factory to reproduce.

• Case: 39mm, platinum 950 on the reference most listings call 52517
• Movement: calibre 7140, automatic, small seconds
• Power reserve: 66 hours
• Dial: ice blue on platinum, applied baton indices
• Strap: alligator leather with a matching deployant or pin buckle

What separates a good replica from a bad one

Case profile first. The 1908 has a domed bezel that flows into slim lugs with a gentle curve. Bad replicas machine this too flat, and the lugs end up looking like slabs. Run a finger along the lug line. It should feel continuous, not stepped.

Second, the dial. The platinum model's ice blue shifts between grey and pale blue depending on light. Cheap reps print a flat pastel that looks wrong indoors. Look at photos taken in window light, not studio light.

Third, the small seconds subdial. It sits at 6 o'clock, and the hand should be thin and slightly curved at the tip. Many reps use a stubby hand borrowed from another model.

Fourth, the crown. Genuine Rolex crowns have a distinct shape on the fluted section and a clean coronet. Reps often have a soft, rounded logo. It is small, but it is where corners get cut.

Fifth, the crystal. A proper 1908 build uses sapphire with a light anti-reflective coating. Plastic or uncoated glass shows up immediately as grey haze.

Movements you will run into

Most 1908 replicas run an automatic 2824-family clone fitted with a small seconds module to move the seconds hand to 6 o'clock. That setup works but adds a layer of gears, and it is the usual source of stutter or a dead subdial after a year. Some thinner builds use a hand-wound movement instead. It keeps the case slim, but if you ever open the back, a hand-wound movement is an obvious mismatch on a watch whose genuine movement is automatic. Ask the seller which movement is inside. If the answer is vague, that tells you something.

Price bands

• Under $120: correct shape from a distance, wrong dial colour, rough finishing, unreliable movement
• $150 to $280: decent case and dial, average bracelet and strap, movement quality varies by batch
• $300 to $600: closest proportions, better dial texture, serviced or upgraded movement, proper alligator-style strap

Above that range you are mostly paying for a name, not a better watch.

Before you buy

Ask for dated photos of the actual unit, not catalog renders. Request a short video with the seconds hand running, so you can see whether it ticks smoothly or stutters. Confirm the strap width at the lugs, since a 20mm strap on a 39mm dress case looks right and a 22mm looks clunky. Check the return policy. And measure your wrist first. A 39mm dress watch wears larger than the number suggests because of the thin bezel, so if you normally wear 36mm, this will feel substantial.

Bottom line

The replica 1908 52517 is a dress watch replica, which means it lives or dies on dial colour and case finishing rather than on specs you can list. Spend in the middle of the market, buy from a seller who answers specific questions with specific answers, and accept that the ice blue dial will never be an exact match. That is the honest ceiling on this one.
