Jaeger-LeCoultre Master Control Date
Jaeger-LeCoultre named a whole collection after a test, a thousand hours of trials for every finished watch, and in 2022 it dressed the plainest member of that family in navy blue and made only 800.

A collection named after a test
Jaeger-LeCoultre introduced the Master Control in 1992. By then the quartz crisis had passed and mechanical watches had survived, and the new line was less about a new look than a new promise. It was the first of the company's collections to carry its in-house 1,000 Hours Control certificate, a test of precision, resistance to temperature and pressure, and robustness against shocks and magnetic fields.
The point of the program was that it tested the finished, cased watch rather than a loose movement. One account describes a thousand continuous hours, roughly six weeks, in six positions and through repeated power-reserve cycles before the watch left the Vallée de Joux, and contrasts that with the 15-day chronometer test that examines the movement alone.
The company itself was by then more than 150 years old. Antoine LeCoultre founded it in Le Sentier in 1833, it took the name Jaeger-LeCoultre in 1937, and since 2000 it has been owned by the Richemont group. The Master Control became its everyday flagship: a round, plain, time-and-date watch meant to show off what the factory could do without any complication to distract from it.
The 2020 reset
In April 2020 Jaeger-LeCoultre rebuilt the line. The Master Control Date grew by a millimeter to a uniform 40 mm, and the steel reference Q4018420 replaced the earlier Q1548420. The dials went back to 1950s company models such as the Futurematic and Memovox for their cues: applied, elongated markers, Dauphine hands, a sunray finish, an applied 'JL' logo at 12 o'clock and a beveled date window.
The bigger change was inside. The automatic caliber 899 gained a silicon escapement and pallet fork, titanium screws and new lubricants, and its power reserve rose from 38 hours to 70 with no increase in case thickness. The company also extended its warranty on the line to eight years.
The 2020 silver-dial Date was priced at about $6,700 to $6,750 in the United States, depending on the report, and €6,950 in Europe.
The blue edition
On April 28, 2022, Jaeger-LeCoultre introduced blue-dial versions of the Master Control Date and Master Control Calendar, each limited to 800 pieces. The Date became reference Q4018480.
The dial is a deep, silky blue with a sunray-brushed finish, framed by a lighter blue minute track. The hour markers are faceted darts with applied Arabic numerals, the hands are faceted Dauphine, and the case lugs are beveled. The watch came on a matching blue calfskin strap with a quick-change system and a folding buckle.
The steel case measures 40 mm across and 8.78 mm thick and is water resistant to 50 meters. Launch pricing was US$8,700 before sales tax; European reports gave €9,150 including VAT and €9,100.
The caliber 899AC
The movement is designed, made and assembled in-house and visible through a sapphire case back. It runs at 4 Hz (28,800 vibrations per hour) with a 70-hour power reserve, close to three days. One review counts 218 components.
For a watch at this price, the finishing is unusually thorough. One reviewer of the steel Date noted Geneva waves on the bridges, polished bevels, heat-blued screws, perlage on the base plate, circular graining on the wheels and a skeletonized gold rotor, and wrote that it went beyond what one might expect at the price.
Why it matters
The Master Control Date is the entry point to Jaeger-LeCoultre's in-house watchmaking, and the blue 2022 edition is the version of that entry point made in a fixed number. Because the case, movement and dimensions match the regular production Date, what sets Q4018480 apart is the dial, the strap and the limited run.
The reference turns up regularly on the pre-owned market. One European dealer listed an example with box and papers at CHF 8,000.

Price record

This is an asking price, not a sale. It is what a seller wanted on the date shown. Asking prices often sit above what buyers pay, but an ask is not a ceiling: a sale can land on either side of it. It is not a value.
By reference price, Jaeger-LeCoultre Master Control Date is number 84 of 100 in the watches entries of the FLOAT 100. 54 of those 100 rest on a realized sale; the rest carry an asking price or a guide value, and each page says which. Rank within the FLOAT 100 itself (63 here) is editorial: how much an object defines its field, not price alone.

How this page is made
- The figure
- One reference price, shown with its own kind. FLOAT does not average it with anything or adjust it for time.
- Realized or not
- A realized price is a completed sale. An asking price, an estimate and a price-guide value are not sales, and are labeled as such wherever they appear.
