if the beat rate says 21,600 then the movement is low beat 21j 2813 so tell your dealer the watches won't have been sent yet as Chinese are on hols till Monday so still time to sort it.

yes looks ok for a £57 beater for work and an ok 1st rep to get you started. Now time to order a better quality rep and you won't believe the difference when you compare.
$318 fora 2824-2 doesn't make you want to buy on a whim when there so many others to buy.who in the UK is going to look and say "thats a nice Tudor i want one of them"
very unlikely you can email but you will have to send it back which will cost you.
