"The K881 was introduced in 1959 and was the first of the firm’s movements to feature a centrally pivoted 360 degree rotor that wound in both directions. The K part of the calibre number was a reference to Kif Flektor, the form of shock protection mechanism used in this unit. Jaeger developed this calibre directly from its famous 493 unit that had been designed specifically at the request of two of the world’s most prestigious watch houses in 1951. Jaeger had first begun production of a self winding calibre, the 476, in 1947, but chose to create a “bumper” type oscillating hammer automatic calibre, rather than one with a bi-directional rotor. The company flirted with rotor design in 1951 with the superb calibre 493, this winding in only one direction, but Jaeger LeCoultre watches with this movement were only sold for a two year period and it wasn’t to be until 1959, when the model for sale here was released, that Jaeger LeCoultre automatics finally entered the modern age. Incidentally, a development of this calibre, the 888, is still manufactured by Jaeger LeCoultre today which is rather something of an indication of how significant, and how brilliantly engineered, these K881 movements were.

There is a very interesting footnote to be added about the design of the K881, which is indicative of the incredible standard to which it was manufactured. Perhaps oddly in some eyes, unlike the other major Swiss top-tier manufacturers, Jaeger LeCoultre never offered a chronometer rated watch in any serious commercial quantities. Tiny numbers of these, literally a few hundred units, were occasionally submitted for independent accuracy testing at one of Switzerland’s Observatories for publicity purposes, but in general, the firm’s output was sold without external time trials. One of the most obvious characteristics of the K881 is that, almost uniquely on a movement of this grade, it has no mechanism for the fine adjustment of the index, this normally being required to minutely tune the unit’s running speed. Astonishingly, the reason for this omission was that the K881 was manufactured as standard to such fine tolerances that it would achieve chronometer rated accuracy as a production norm, without the need for any further adjustment. The American publication “WatchTime” ran a test on the K881 and the various other related Jaeger LeCoultre movements from the same era in its August 2003 edition ( pages 88 to 91), concluding that this mechanism “embodies superlative expertise that emphasises skilful, precise craftsmanship and surface beauty”. Further mention is made that in its very slightly revised form, this same movement type was officially certified as a chronometer and sold in tiny quantities as the “Chronometre Geomatic”, a model that commands a huge price today on account of its scarcity."
