Circa mid to late 1800s. 41.86 mm in diameter.
The white enamel dial is signed H. PERREGAUX LOCLE and is in excellent shape.The spring detent CHRONOMETER movement is stamped H PERREGAUX LOCLE N 13155 Spring detent chronometer escapement. The balance staff swings freely and the hairspring is good but it doesnt run. It seems that the round gear wheel (last 2 photos) may have issues and will not lock down when winding the mainspring, thus no power.
If you apply pressure to the barrel with a watch key, the chronometer will run. You dont run across these pieces too often in any shape.
