At Watches & Wonders 2025, Cartier did something the Tank Louis Cartier hadn't seen since 1974: it moved away from hand-winding. The WGTA0357 replaces the Caliber 1917 MC of the predecessor reference WGTA0191 with the automatic Caliber 1899 MC. Collectors in the trade mostly call the model the Tank Louis Auto or TLC Auto, though some refer to it as the Tank LC Automatique Large. The case stays at 38.1 × 27.75 mm, so Cartier didn't touch the proportions, only the movement inside.
## Dial and Case: The Visible Changes
The new caliber comes with a new dial too: silver, guilloché, Roman numerals, a different finish than the hand-wound version. The bezel remains yellow gold 750, polished, carrying the classic Cartier look forward. Anyone familiar with the WGTA0191 will notice the difference mainly in the power reserve behavior, not in the look from a few steps away.
## The Rose Gold Companion and What It Means for the Market
Alongside the WGTA0357, Cartier released the reference WGTA0346 in rose gold with a brown alligator strap, same technical base, different material choice. Launching two versions at once is no accident for Cartier, it signals that the brand is positioning the automatic Tank Louis as a model line in its own right rather than a niche variant. For valuation purposes, that means comparisons with the hand-wound WGTA0191 only tell you so much, since the two calibers appeal to different buyer groups. Anyone trying to place the WGTA0357 should treat the Caliber 1899 MC as its own market parameter, not a footnote to the older reference.
Brand profile: Cartier
Cartier watches (Santos, Tank, Ballon Bleu) are popular targets for counterfeiters. The distinctive design (Roman numerals, blue sword hands) is recognizable — but also easy to copy.
- Sapphire cabochon crown: on genuine pieces it's SET INTO THE METAL (bezel-set); on fakes it's usually GLUED. Test: loupe — adhesive residue around the edge = fake.
- Bracelet screws: genuine Cartier bracelets ALWAYS have visible screw slots. Pins instead = fake.
- 'Swiss Made' at 6 o'clock: MICROPRINTED directly beneath the 6 o'clock marker. Fakes often omit it or print it crooked.
- Guilloché pattern: under 10x magnification, EXACTLY parallel and uniformly deep. Irregularities = fake.
Serial number format: Cartier serial numbers: alphanumeric, on the case back. Older models: number located between the crystal ring and the case. New purchases come with a Cartier passport.
