Among all the classic Cartier Tank watches, if I were to choose one for everyday wear, I would definitely select the TANK Solo. However, this choice may be influenced by the latest TANK MUST introduced in 2021. This year, the brand launched the brand new TankMust series of watches, featuring the iconic square case measuring 29.5mm x 22mm and a thickness of 6.6mm, adorned with 40 VVS-grade diamonds weighing approximately 0.48 carats. The dial is silver-plated with Roman numeral markers, and the brand's signature sword-shaped blued steel hands, along with sapphire crystal glass. The crown is set with a unique natural blue spinel. The imported silk calfskin strap is an original interchangeable strap with a one-year warranty, allowing for free replacement of any cracked or damaged straps within the year. The case has been redesigned for smoother, rounder lines with a 316L stainless steel rectangular case, polished and brushed with precision. Additionally, the watch features a quick-release strap function, significantly enhancing everyday wear comfort and convenience. It's great for both gifting and personal use!
