That's the way it works with my two Rolexes, a 1675 GMT (1570 mvt.) and a 116520 Daytona (4130 mvt.). The GMT gains about 2 sec/day dial up, loses 3 sec/day with crown down, and loses 7 sec/day or more crown up. The Daytona is fast regardless of position, 5 sec/day dial up, 1 sec/day crown down, and 2 sec/day crown up. This is according to my Timegrapher.
