The fastest riser of the 26mm set: dealer averages up 38.6 percent from December 2025 to May 2026.
It is also the riskiest: 40+ years old, acrylic crystal, no real water resistance, and plenty of examples with replaced dials and parts. Unpolished full sets are the ones to own.
The 1970s original of the ladies' Datejust craze, small, gold-bezeled, and dripping with disco-era charm. Sigma dials, marked with small sigma symbols flanking 'T SWISS T', date the earliest and most collectible examples.
Five years ago these were $2,000 watches. The vintage-petite wave, driven by stylists and secondhand-luxury platforms, has roughly doubled them, and the best champagne dials now get competed for at auction.
Our verdict: Highest momentum, highest risk. Only buy full-set, original-dial examples from dealers with a warranty.
