Vittorium AT is a historically documented Swiss-made dive-watch line. A 2014 collection overview describes two core models: the 42 mm AT 42, with an ETA F06.111 movement, and the 48 mm AT 48, with an ETA 251.272 chronograph movement. The same overview lists 500 m/50 ATM water resistance for the AT 48 and says the AT 42 shares its other technical features. These are historical published specifications—not confirmation of current production or of any particular watch’s condition today.
What is a Vittorium AT watch?
Vittorium AT is a dive-watch range described in historical brand material and a 2014 collection overview. The brand’s July 2010 archive post presented the line as Swiss-made, with steel construction, chronograph timing, rubber straps, luminous dial markings and a turning bezel. Those are the brand’s claims, not independent test findings.
The 2014 overview identifies AT 42 and AT 48 within a broader Vittorium range that also included DEEPDIVER and WHALE. It is a useful record of how the collection was presented at the time, but its publication date does not establish that the line remains in production. No current catalog, inventory, authorized-dealer list or warranty terms are established by the available sources.
What is the difference between AT 42 and AT 48?
The principal reported differences are case diameter and movement. The 2014 overview describes the AT 42 as a 42 mm watch with an ETA F06.111 movement, and the AT 48 as a 48 mm watch with an ETA 251.272 chronograph movement. It says the AT 42’s remaining technical features match the AT 48’s. Confirm the exact reference, since specifications may differ among individual models.

| Model | Reported case size | Reported movement | Reported water resistance |
|---|---|---|---|
| AT 42 | 42 mm (MasterHorologer, 2014) | ETA F06.111 (MasterHorologer, 2014) | Not separately stated for AT 42; the overview says its other technical features match AT 48 (MasterHorologer, 2014) |
| AT 48 | 48 mm (MasterHorologer, 2014) | ETA 251.272 chronograph (MasterHorologer, 2014) | 500 m/50 ATM, as reported in the 2014 overview (MasterHorologer, 2014) |
Those differences suggest a practical starting point for choosing between examples: consider how a 42 mm or 48 mm case wears on your wrist, whether you want a chronograph, and the specific watch’s condition and service history. The sources do not establish comparative accuracy, durability or independent performance, so they do not support calling one model better overall.
Is the Vittorium AT rated to 500 m?
The 2014 MasterHorologer overview reports a 500 m/50 ATM rating for the AT 48. It says the AT 42 shares the AT 48’s other technical features, but does not separately give an AT 42 water-resistance figure. Vittorium’s 2010 archive also described the AT 42 as reaching 500 m. These are historical published claims, not independent test results or evidence that a particular watch still meets its original rating.

A rating describes a properly built and maintained watch; it cannot establish the seal condition of an older example. Have a qualified watchmaker pressure-test a prospective purchase before using it in water, especially before swimming or diving and after service or long periods without maintenance.
Where does AT sit alongside DEEPDIVER and WHALE?
The 2014 overview listed DEEPDIVER and WHALE alongside AT. Their specifications provide historical context for the collection, not a current product comparison.

| Collection | Reported sizes | Reported water resistance | Other reported detail |
|---|---|---|---|
| DEEPDIVER | 47 mm (MasterHorologer, 2014) | 200 m (MasterHorologer, 2014) | ETA F06.111 movement (MasterHorologer, 2014) |
| WHALE | 42 mm and 22 mm (MasterHorologer, 2014) | 100 m (MasterHorologer, 2014) | No movement specified in the overview |
Vittorium’s older brand archive separately described DEEPDIVER as having sapphire crystal, 316L steel, an ETA movement and 20 ATM/200 m water resistance. Those details are promotional brand claims and should not be treated as independent verification of an individual watch.
Can you still buy a Vittorium AT watch?
Current production and availability are not established. The historical archive lists references including AT 260154, AT 260157, AT 260180, AT 260191, AT 260200 and AT 260202, but those listings do not prove that any reference is currently available or that old prices reflect today’s market. Check current sellers for a live offer and assess the seller’s identity, return terms and documentation rather than assuming a watch is new, authorized or covered by a current warranty.

What to verify before buying a specific AT watch
Because exact references and condition matter, request clear photographs and documentation before committing to a purchase. Use these checks to evaluate the individual watch rather than relying on a collection-level specification.

- Identify the watch. Ask for photographs of the dial, caseback, reference and serial markings. Compare them with any accompanying papers or other documentation; the historical reference list alone does not authenticate a specific example.
- Confirm the movement and functions. Ask the seller to identify the calibre and demonstrate the watch’s functions. For the model descriptions in the 2014 overview, AT 42 is paired with ETA F06.111 and AT 48 with ETA 251.272 chronograph.
- Ask about service and parts. Request service records, dates and details of work performed, and ask what parts were replaced. The historical sources do not establish a current service network or parts source.
- Assess the condition and transaction terms. Check the case, crystal, bezel, strap and visible signs of repair, and get the seller’s return terms in writing. Treat claims of Swiss manufacture, originality and water resistance as claims to verify for that particular watch.
- Test before water use. Have a qualified watchmaker pressure-test the watch; do not rely on an old rating as proof of present-day water resistance.
