The Tank Solo, one of Cartier's most iconic and best-selling watches, was once so popular that it was even nicknamed the "stewardess watch" due to its mainstream appeal. Over the years, it has undergone several name changes, and today, it is sold as the Tank Must.
Previously available for around 2 million KRW, the Tank Must served as an entry-level Cartier timepiece, featuring a sleek stainless steel case paired with a black leather strap, making it an instant classic. However, rumors of its discontinuation began circulating as availability decreased. Eventually, it was said to be sold only to VIP customers, and now, it is exclusively available via Cartier’s official online store and Maison Cheongdam in Korea.
Luxury brands that once resisted online sales are now strategically using digital platforms for their best-selling models—a clear sign of the changing times.
Technological Advancements: The Introduction of ‘SolarBeat’
Alongside new sales strategies, Cartier has also made technical advancements.
Since 2021, the Tank Must lineup has incorporated SolarBeat technology, a solar-powered movement that eliminates the need for battery replacements.
Japanese watch brands like Seiko and Citizen have long utilized solar charging technology, but Cartier was the first Swiss luxury brand to introduce a solar-powered quartz watch.
In 2025, Cartier launched the SolarBeat Version 2, extending the rechargeable battery life to 16 years.
Why Did Cartier Introduce SolarBeat?
Cartier has always been a favorite among female consumers, but many automatic models had a short power reserve. If left unworn for two days, the watch would stop, requiring frequent resetting.
SolarBeat was a strategic solution:
Cartier recently extended its warranty to 8 years, requiring a more sustainable and low-maintenance quartz movement.
The high demand for free battery replacements at Cartier’s only authorized service center in Korea may have been a concern.
SolarBeat reduces the need for battery replacements while embracing eco-friendly watchmaking.
Initial Issues with SolarBeat & The Release of Version 2
SolarBeat Version 1 was not perfect.
Customers reported frequent movement failures and initial defects.
The repair process required sending the watch to Switzerland, causing long wait times.
Cartier responded by offering a swap to traditional quartz models, but standard quartz production has since been phased out.
(Is this why Cartier has never officially declared the discontinuation of regular quartz models? 🤔)
In 2025, Cartier launched SolarBeat Version 2, improving battery performance and stability. It remains to be seen how effectively these early issues have been resolved.
Design & Sustainability – The Future of Cartier Watches
The SolarBeat technology is uniquely implemented without compromising the classic Tank Must design.
The dial itself acts as a solar panel, preserving Cartier’s signature aesthetics.
This innovation maintains design integrity while integrating modern technology.
Cartier’s approach reflects a broader trend in the luxury watch industry—combining sustainability with technological advancements.
Tank Must SolarBeat – 2025 Model Pricing & Specifications (as of March 4, 2025)
Model WSTA0089 (Small, Women’s) – 4,990,000 KRW
Model WSTA0090 (Large, Men’s) – 5,250,000 KRW
The price remains the same as traditional quartz models.
Standard battery replacement costs:
- Independent watchmaker: ~30,000 KRW
- Official Cartier service: ~60,000 KRW (free within the 8-year warranty)
SolarBeat rechargeable battery replacement: - ~200,000 KRW at independent repair shops (but limited availability).
Unlike standard dials, the SolarBeat dial contains solar panel technology, which may lead to higher maintenance costs. Repairs must be handled exclusively by Cartier’s official service center.
Evolution of Luxury Timepieces
The Cartier Tank Must SolarBeat is more than just a new watch model—it represents how luxury brands are adapting to modern sustainability and efficiency trends.
Luxury watches are evolving, not just in design but also in their technology and long-term usability. The Tank Must SolarBeat is a prime example of how luxury brands are embracing change without compromising heritage.
As luxury brands continue to innovate, will more high-end Swiss watchmakers follow Cartier’s lead in solar-powered technology ?
