Detent chronometer escapements were used during the 19th century in high precision timepieces. The detent was expensive to produce and with the start of the industrial revolution at the end of the 19th century, more efficient and economical escapements were made. One of the most important innovations was the Guillaume balance that could be used with the lever escapement and ensure similar precision timekeeping, thus making the detent less favorable in the horological field. This type of escapement was constructed so there was only one impulse, compared with the lever that had two. This helped to reduce friction and increase reliability.

The present detent chronometer from the end of the 19th century is a technical marvel, and also beautifully designed. The chased and engraved hunter case is reminiscent of the art nouveau style. The center features a lion’s head set within a floral garland with buds and tendrils. In excellent overall condition, this example watch presents an opportunity for a collector to own one of these rare chronometers.
