Rolex Oyster Perpetual Datejust Caliber 1065 Service & Repair

Service Overview

This page documents the professional service and repair of a vintage Rolex Oyster Perpetual Datejust powered by the Caliber 1065 movement. Watches from this era represent an important transitional period in Rolex engineering, combining proven mechanical reliability with the refinement that helped establish the Datejust as one of the most recognizable luxury wristwatches in the world. Proper servicing of these early automatic Rolex movements is essential to preserve accuracy, and longevity.

Condition and Servicing Notes

The example serviced here was found to be in excellent original condition, showing no corrosion, excessive wear, or compromised components—a testament to both Rolex manufacturing quality and careful ownership over the decades, although it has been some time since the last service as movement had accumulated hardened oil and debris seen in the pictures. The movement was fully disassembled, cleaned, inspected, lubricated, and adjusted to ensure optimal performance while preserving original parts and finishes.

Vintage Rolex Datejust watches with the Caliber 1065 remain highly regarded for their mechanical simplicity, serviceability, and historical significance, making proper servicing by an experienced vintage watch repair specialist especially important.

Caliber 1065 Movement History

The Rolex Caliber 1065 was introduced in the mid-1960s and is part of the early generation of Rolex automatic movements that laid the foundation for later calibers such as the 1570 and 3035. Produced around 1965, the 1065 is a chronometer-grade, bi-directional automatic movement featuring a free-sprung balance, a hallmark of Rolex’s commitment to long-term rate stability and shock resistance. This design reflects Rolex’s emphasis at the time on reliability over convenience, particularly in professional and everyday wear watches.
