The micro-mechanical engineering behind the OMEGA Speedmaster Date 39mm is a testament to historic Swiss craftsmanship. This premium model, reference 3513.50.00, runs on the highly reliable OMEGA caliber 1152 automatic chronograph engine. This robust movement architecture is heavily praised by watchmakers for its excellent serviceability and structural shock resistance. Featuring an integrated date window and a multi-link stainless steel layout, it balances high-frequency engineering with supreme daily style versatility.

Technical Diagnostics and Kinetic Calibration Values

Our comprehensive mechanical restoration completed in July 2026 has brought this caliber 1152 back to immaculate performance parameters. Diagnostic testing yields an exceptional balance wheel amplitude of 296 degrees and a daily rate variance of plus one second per day. To ensure strict structural integrity, the automatic reversing wheel, power mainspring, and internal synthetic rubber seals were fully replaced. The face is protected by an ultra-hard, scratch-free sapphire glass sheet block.

Materials Specification and Full Set Hardware Configuration

The total physical mass of the watch stands at a solid 133g, confirming robust case wall properties.
