Mens' Dress model takes 103 [magnet set] and 104 [auto-set]. Ladies' Oval and Cushion take 101 [magnet set] and 102 [auto-set]. The modules are identical in dimension and are interchangeable; the sole functional difference is the height of the LED digits [about .5mm taller on the mens' model]. The only exception to this is the P3L, which uses a 104 module in a stainless Cushion case.
