The Vacheron Constantin Overseas Reference 42052 is a highly collectible, first-generation luxury sports watch launched in the late 1990s. This specific variation combines a mid-size 35mm stainless steel case with a rare, historically significant Sigma silver dial.

• Case Size: 35mm diameter. This offers an elegant, vintage-leaning proportion that wears similarly to a classic 36mm dress watch. 

• Movement: Automatic Caliber 1311. It features a quickset date complication at the 3 o'clock position.

• The "Sigma" Dial: Features lowercase Greek "Sigma" letters (σ) flanking the "OT SWISS MADE TO" text at the bottom of the dial. This certifies that the hands and hour indices are crafted from solid white gold rather than steel.

• Design Language: Designed by Dino Modolo and Vincent Kaufmann, featuring the iconic Maltese Cross-inspired bezel and integrated steel bracelet links.

• Caseback: Solid stainless steel caseback engraved with the signature Amerigo Vespucci three-masted ship.
