One of the important characteristics of the Mark 11 was its need to be highly antimagnetic, achieved through the iron dial and iron dust cap, which creates a Faraday cage, protecting the movement from magnetic fields. Inside the watch, is perhaps its most impressive aspect, the JLC Calibre 488/SBr - a chronometer grade movement with a hack device and centre seconds.

It is rhodium brass finished with Geneva stripes. It was the precursor to the famously accurate Geophysic movement, released in 1958. The movement itself is marked with the British Broadarrow, and is distinctive in its look with its stop lever. The Jaeger LeCoultre Mark 11s were renowned for their timekeeping accuracy, as this was a fundamental specification required by the British Armed Forces. As a result, these watches were regulated in five positions and tested in temperatures ranging from -5 degrees to 46 degrees over a 44-day testing period.

This was conducted in the chronometer workshop of the Royal Greenwich Observatory in Herstmonceux. The item "Jaeger lecoultre MK11 Cal 488.
