Jaeger-LeCoultre's historic instrument

Jaeger-LeCoultre’s latest is a tribute to science and watch-making precision.

ONE OF the most important models in the Jaeger-LeCoultre heritage, the Geophysic chronometer has a special history.

It was created in 1958, the International Geophysical Year, and has served as the quintessential symbol of precision and reliability with a design of undeniable purity.

Its calibre movement is derived from military watches and incorporates the best watch-making technology of that time: a stop second for precise time-setting; a glucydur balance for stability through changes in temperature and fitted with a shock absorber; a “swan neck” index for micrometric adjustment; and the essential soft-iron inner case that protects this exceptional mechanism from the effects of magnetism.

Inspired by the original Geophysic model, the design of three new watches enhances the legibility and aesthetic distinction of the historic instrument.

The models paying tribute to the Geophysic feature a slightly larger diameter of 38.5 mm to meet the comfort requirements of the 21st century.

In the spirit of the calibre 478BWSbr, based on research linked to the Geophysical Year, they are equipped with the Jaeger-LeCoultre Calibre 898/1, considered one of the most precise and reliable in-house automatic movements on the market today.

This exceptional movement combines the best of technology: a stop second for accurate time-setting; a frequency of 28,800 vibrations per hour for high precision; a balance with micrometric adjustment by means of screws set into the rim; Spyr gears for smooth transmission of torque in the gear train; automatic winding with ceramic ball bearings that require no lubrication, and more, all without counting the soft-iron inner case that protects the mechanism from the effects of magnetism.

Each version of the Geophysic watch is fitted with an alligator leather strap secured by an unusual pin buckle in colours matching the metal of the case: black for the steel model and chocolate brown for the pink gold variation. – William K.C. Kee
