This multicoloured La Californienne reworked vintage Cartier Tank watch features a 31 mm case plated with yellow gold. It boasts the signature cabochon crown, Roman numerals, a blue dial, and Cartier and La Californienne branding. The tan leather wrap bracelet is hand painted with blue and pink stripes. To use Ke$ha's words, ‘Tick-tock on the clock, but the party don't stop, no.’ Not when you have this La Californienne watch on your wrist.

The watches are pre-owned/vintage and have been customised by the brand, therefore the ‘made in’ information refers to where the watch was customised rather than the place it was manufactured.
