The Vacheron Constantin Overseas Ref. 16050 is a first-generation lady’s luxury sports watch, typically measuring 24mm to 25mm in case diameter. This specific reference is a quartz-powered timepiece designed for those seeking the iconic Overseas silhouette in a more delicate, feminine size. 

• Case Size: Most commonly cited as 24mm, though some listings and sources may refer to it as 24.5mm or 25mm.

• Movement: Equipped with a high-precision Quartz movement.

• Material: Constructed from Stainless Steel, featuring the signature Overseas integrated bracelet with Maltese cross-inspired links.

• Dial: The "Beige" dial is a rare and elegant variant, often described in similar listings as having a sunburst finish or potentially leaning toward a "salmon" or "champagne" tone depending on the specific production year.

• Diamond Setting: This specific model features a factory diamond-set bezel, which elevates the sporty aesthetic to a dressier level.

• Water Resistance: Historically rated at 15 ATM (150 meters), which is exceptionally high for a lady's watch of this size, though resistance should be verified on pre-owned pieces.
