Start with the watch’s complete model reference, then check whether it has a date display and compare its details with Rolex documentation for that exact reference. For example, Rolex identifies reference 124060 as a no-date Submariner and 126610LN as a Submariner Date. A feature match can help identify a model, but it cannot by itself authenticate a watch or establish its exact production year.
How do you identify a Submariner by its reference number?
Find the complete reference on the watch’s paperwork or other documentation, then use it to locate the corresponding Rolex model information. Treat the reference as the starting point: do not try to date a vintage watch precisely from its appearance or from the reference number alone. Rolex’s published current examples show that different references can have distinct configurations and movements, while the available official material does not provide a complete chronology for every historical reference.

- Record the full reference. Use the complete number shown in the watch’s documentation rather than relying on a partial number or a verbal description.
- Look up that exact reference in Rolex documentation. Confirm that the model name and listed specifications match the reference you have.
- Compare the physical watch with the documented features. Check the date display, case size, bezel, dial, hands and bracelet where the documentation specifies them.
- Keep identification separate from authentication. A matching reference and set of visible features do not prove that the watch or all of its parts are genuine.
A reference identifies a model configuration; it should not be treated as a universal code that, by itself, gives a definitive production year. The official Rolex material cited here does not establish a serial-number lookup method for dating every vintage Submariner.

How can you tell a Submariner from a Submariner Date?
Check the dial at 3 o’clock. A Submariner Date has a date display with a Cyclops lens over it; the no-date Submariner has neither. Rolex’s current product pages distinguish reference 124060 as the no-date Submariner and 126610LN as the Submariner Date.

| Reference | Configuration | Date and Cyclops | Case size | Bezel | Calibre | Water resistance |
|---|---|---|---|---|---|---|
| 124060 | Submariner without date | No date display; no Cyclops lens | 41 mm | Black Cerachrom | 3230 | 300 m |
| 126610LN | Submariner Date | Date display with Cyclops lens | 41 mm | Black Cerachrom | 3235 | 300 m |
Specifications in this table are from Rolex’s official product pages for references 124060 and 126610LN. These are current examples, not a complete guide to older Submariner references. The shared case size, bezel description and water-resistance rating also show why one feature alone may not distinguish two models.
Which features should you compare with the reference?
Use details that Rolex publishes for the exact reference, rather than assuming that every Submariner from a given era looks the same. A useful comparison checks:
- Date configuration: whether a date is shown and, on the Date model, whether a Cyclops lens sits above it.
- Case: the listed case size and material.
- Bezel: the bezel material, color and markings described for the model.
- Dial and hands: compare their documented appearance, but do not treat a visual match as proof of authenticity.
- Bracelet: check the type and material specified for that reference.
- Movement and water resistance: use the values Rolex publishes for the reference; do not transfer specifications from a newer or different model.
If a watch differs from its reference’s documented configuration, the discrepancy is a reason to seek an expert assessment—not, on its own, a definitive conclusion. Parts may have been changed, and older watches require comparison with documentation for their own generation.
What do Submariner history and dates tell you?
Rolex’s official history provides several useful milestones, but these dates describe the model line and its published specifications—not the production year of an individual watch:
- Rolex says the Submariner launched in 1953 with a guaranteed water resistance of 100 m (330 ft).
- The Submariner Date was unveiled in 1969 as a version with a date function.
- Rolex says the Submariner’s water-resistance guarantee reached 300 m (1,000 ft) in 1989.
Use these milestones as context only. They do not replace a reference-specific history or establish the exact age of a particular watch.
Does a matching reference prove a Submariner is genuine?
No. Matching the reference and visible features helps identify the model, but it is not authentication. Rolex states that only official Rolex retailers are allowed to sell and maintain its watches, and that authorized retailers guarantee the authenticity of each part. For an assessment of a specific watch, consult an official Rolex retailer or a qualified watch professional; do not rely on a visual checklist or a reference match as proof.
