its not so easy as it sounds
you need some basic knowledge about Rolex cases - or some good pics -
i whould stay away from machines - the work is faster done but also your watch is faster [censored] up
take your time ! relax ! have fun a few beer help sometimes
careful with matte spray ! - wrong spray = ruined dial
careful with baking and bleaching ! - 30 sec too long - adios dial, hands, insert ...
get some GOOD tools -start with sreewdrivers
cheers,
Frank
