About the Master Control family
The Master Control was introduced in 1992, when Jaeger-LeCoultre began testing each watch for 1,000 hours before it left the manufacture, a test that gave the line its name. It is a classic round watch with a simple dial and a sector-style layout on some versions.
The catalog includes time-and-date models with caliber 899, chronographs with caliber 759, calendar and geographic models, in stainless steel and pink gold. Dealers identify the function and generation from the reference and check the strap or bracelet and the papers.
