Choose the Tank Must SolarBeat if you want a steel Tank with a photovoltaic quartz movement that recharges in light. Neither family has one fixed specification, so compare reference numbers before deciding.
Compare the exact references, not just the names
Tank Louis Cartier and Tank Must SolarBeat are distinct ways to wear Cartier’s Tank design, but each name covers configurations that differ. The examples below make the comparison concrete; they are not a claim that every watch in either family has these specifications.
| Reference | Movement | Case and material | Strap or bracelet | Water resistance |
|---|---|---|---|---|
| Tank Louis Cartier WGTA0011 | Hand-wound mechanical, calibre 1917 MC | 18K rose gold; 33.7 × 25.5 mm, 6.6 mm thick | Semi-matt brown alligator strap | 3 bar/about 30 m |
| Tank Must SolarBeat WSTA0120 | Photovoltaic quartz | Steel; 33.7 × 25.5 mm, 6.6 mm thick | Calfskin strap | 3 bar/about 30 m |
| Tank Must SolarBeat WSTA0122 | Photovoltaic quartz | Steel; 33.7 × 25.5 mm, 6.6 mm thick | Steel bracelet | 3 bar/about 30 m |
Cartier’s international WSTA0120 listing and UK WSTA0122 listing specify the SolarBeat examples. The WGTA0011 product page documents the rose-gold manual-wind example; its listing is a documented configuration, not confirmation of current stock. Cartier’s US collection also shows Tank Louis configurations with different movements, including quartz and manual winding, so confirm the movement on the exact reference you are considering.
Which movement routine suits you?
SolarBeat: recharge through light
Cartier describes SolarBeat as a Swiss-made photovoltaic movement: its battery recharges when exposed to daylight and artificial light. That removes the daily winding habit, but it does not mean the watch never needs light exposure or that every production version has the same stated autonomy.

Cartier’s SolarBeat guide versions give different figures. An earlier guide claims at least 16 years without battery replacement and about five months of autonomy when fully charged. A later guide, for watches sold after 1 November 2024, gives about 24 months of autonomy when fully charged. These are Cartier’s version-specific manufacturer claims, not independent performance-study results; use the guide applicable to the watch’s sale date rather than combining the figures.
Tank Louis: check whether the chosen reference is mechanical
The WGTA0011 uses hand-wound calibre 1917 MC, but Tank Louis Cartier is not synonymous with manual winding: Cartier lists other configurations, including quartz. For one separate model, the Tank Louis Cartier extra-flat W1560017, Cartier’s user guide calls for daily winding and reports around 40 hours of power reserve. That routine and reserve apply to that guide’s reference, not automatically to WGTA0011 or every Tank Louis.

How do the materials, size, and wearing options compare?
The cited large models share stated case dimensions of 33.7 × 25.5 mm and a thickness of 6.6 mm. That makes their listed size directly comparable, but it does not guarantee the same feel on the wrist: material, strap or bracelet, and individual wrist shape also affect fit. Trying on the exact reference is more useful than deciding from the dimensions alone.
The cited Louis reference is 18K rose gold with a brown alligator strap; the SolarBeat examples are steel, with either a calfskin strap (WSTA0120) or steel bracelet (WSTA0122). Those are meaningful differences in appearance and configuration, not interchangeable details. Check the reference and included strap or bracelet rather than assuming the family name specifies one.

What does the water-resistance rating mean?
The cited large examples are rated to 3 bar, approximately 30 metres. Treat that as a modest rating, not an endorsement for diving or every water activity. Cartier’s listing establishes the rating; it does not establish suitability for a particular activity.
Quick Recap
How to make the choice
- Start with the movement. Pick a specific manual-wind Louis if you want a mechanical watch and accept winding; consider SolarBeat if light-recharged quartz better fits your routine. Verify whether a Louis reference is mechanical or quartz.
- Choose by material and configuration. The WGTA0011 example is rose gold and alligator; the cited SolarBeat references are steel, with calfskin or bracelet options.
- Check fit in person if possible. The cited large examples have matching case measurements, but those numbers alone do not settle wrist comfort.
- Verify the SolarBeat guide version. Its autonomy claims differ between the earlier guide and the guide for watches sold after 1 November 2024.
- Confirm local price and availability. Cartier’s pages represent different regional markets and configurations, so they do not establish a like-for-like current price or inventory.
