[nolaclarky]

i have a '93 79090 black tudor sub date. the lume is gone and i like me some lume. i was thinking of sending away for a service plus new dial and hands (will have original dial and hands returned of course). i am curious what the 79090 service dials look like? luminova, super luminova, white gold surrounds, swiss, swiss made or still use t swiss t even though no tritium? thank you!
