Rolex Oyster Precision Ref. 6425 – c. 1956

Serial: 1298XX | Manual Wind | Clean, Minimalist Design

Why It Matters

The Rolex Oyster Precision Ref. 6425 represents a purist’s approach to vintage Rolex—clean, reliable, and timeless. Produced in the mid-1950s, this reference sits at the intersection of Rolex’s earlier, dressier era and the rugged functionality that would come to define the brand in the decades ahead.

The 6425 features a 36mm stainless steel Oyster case, paired with a classic manual-wind movement and no date complication—an increasingly rare configuration in a modern landscape dominated by feature-heavy pieces. Its simplicity is its strength, allowing the clean dial layout and balanced proportions to shine through. The screw-down crown and Oyster case construction reflect the early implementation of Rolex’s water-resistant technology.

This example, dating to around 1956 based on serial 1298XX, is a snapshot of post-war Rolex design: slim profile, manual wind engagement, and a focus on practical elegance. It’s a perfect everyday vintage piece or a smart entry into the world of pre-Crown Guard Rolex.
