Nice and technically interesting pocket watch.
Watch is rather big, diameter is 59mm, height is 69mm.
Movement features one of the most advanced complications - tourbillon with spring detent escapement.
It's signed by Harris in Wolverhampton on the plate.
However, tourbillon and escapement should be later modifications to the movement, custom watchmaking work.
Nice and interesting piece.
Condition

Movement is running as it should.
Case is in ok condition, with minor wear.
