PROBLEM TO BE SOLVED: To provide a platform escapement module which can be easily integrated with a movement.SOLUTION: A platform escapement assembly includes: a balance 3 having a roller 4; a balance spring 5, and an escape wheel 6 controlled by a pallet 7 which collaborates with the roller 4. An escapement holder 10 comprises a first spacer 20 and a second spacer 21 including a first bearing surface 22 and a second bearing surface on both sides of a bottom surface 11, respectively. The first bearing surface 22 and the second bearing surface support a first complementary surface 24 and a second complementary surface of a balance holder 30 on both sides of an upper surface 11A, and the upper surface 11A has flexibility higher than that of the bottom surface 11. Thus, when the second complementary surface is fixed at a suitable position on the second bearing surface, the first complementary surface 24 can move with respect to the first bearing surface 22 while receiving a force perpendicularly applied to the upper surface 11A. |
