Abstract
Platform escapement assembly (1) comprising a balance (3) with a roller (4), a balance spring (5), and escape wheel (6) controlled by a pallet lever (7) cooperating with said roller (4).An escapement bridge (10) comprises, on both sides of a bottom surface (11), first (20) and second (21) spacers respectively comprising first (22) and second (23) bearing surfaces for receiving first (24) and second (25) complementary surfaces of a balance cock (30) on both sides of a top surface (11A), and said top surface (11A) is more flexible in bending than said bottom surface (11), so as to allow mobility, as a result of a perpendicular force applied to said top surface (11A), of said first complementary surface (24) relative to said first bearing surface (22) when said second complementary surface (25) is locked in position on said second bearing (23) surface.
