Price a watch from a photo.

Worth reads the dial, the case and the bracelet, names the model as closely as the photo allows, and says plainly when it can only see part of the watch.

Worth result for a Rolex Two-Tone Oyster Bracelet: estimated value $1,800 to $3,500, low confidence at 30%. The reasoning says only the crown clasp and two-tone bracelet are visible, the watch head and model are unknown, so this is a bracelet-level estimate, and that a full two-tone Rolex watch would sell far higher.
A real result: only the clasp and bracelet were in frame, so Worth priced a bracelet and said so.

Low confidence is the right answer to that photo. Show Worth the dial, or tell it the reference, and it prices the watch instead of the bracelet.

What Worth reads from the photo.

The model
The brand and model family, from the dial, the case shape, the bezel and the bracelet.
The metal
Steel, two-tone or gold, which is often the largest step in price within one model.
The condition in view
Scratches, bracelet wear and the state of the crystal, where the photo shows them.
What is not in the photo
A clasp or a bracelet on its own is priced as that, and the answer says a full watch would be worth more.

Each answer names the one thing that would move the estimate most. Tap a quick answer, type a line, or take the follow-up photo: the price is worked out again the moment it is taken.

  1. Reference number

    It is the exact model. Two watches that look alike from the front can be different references.

    Show WorthType it, or photograph the case back or the warranty card.

  2. Serial number and year

    It dates the watch and ties it to its papers.

    Show WorthThe year is enough. Type it, or photograph the card.

  3. Box and papers

    A full set sells for more than the watch alone, and papers support where it came from.

    Show WorthPhotograph the set, or add the detail: “full set, 2019 card”.

  4. Service history and originality

    Collectors pay for an original dial, original hands and an unpolished case. Replaced parts change the price.

    Show WorthAdd what you know: “serviced 2022, original dial”.

  5. Bracelet and condition

    Stretch, missing links and deep scratches come off the price.

Questions.

Can it identify the exact reference?
Sometimes, from the dial, bezel and case alone. When several references look the same from the front, it names the family and asks for the reference, which narrows the range in one step.
Can it tell whether a watch is genuine?
No. A photo cannot authenticate a watch. Worth prices what the watch appears to be. Before a purchase, have it opened and checked by a watchmaker or a dealer you trust.
Do box and papers change the estimate?
Yes, once Worth knows about them. Add “box and papers” as a detail or photograph the set, and it prices the watch again.
