Chopard Imperiale Automatic 40mm

Breitling 21/Valjoux 7751 Questions
Proud owner of my very first Breitling which just arrived today, as well as my very first automatic chronograph (Montbrillant Datora). As I am new to this movement I want to make sure to treat it right. My research has shown that you should not change the day/date during the 8pm-2am timeframe. I have also read that the base movement, the 7751, has a moon phase feature (obviously not used on the Datora) that cannot be used during the 12am-6am timeframe. My questions are, is it ok to manually wind the watch via the crown during these timeframes? I usually give the crown a couple of twists when I take it off at night to give it some power until the morning. And second, when Breitling modifies the 7751, does it remove the moonphase feature completely? Should I play it safe and go past 6am in the morning if I have to set the date? I know the moonphase on the 7751 uses the same crown position as the date, and until I get familiar with this watch I am sure I will twist the crown in the wrong

Need Help Eterna Kontiki 20
I just bought an early 1960s Eterna-Matic Kontiki 20. It has the Kontiki orginal band, and the date display. The dial is silver with black markers. The watch runs good, but is in dire need of a cleaning. I paid 140 for it. I dropped it off at the watchmaker. yesterday and they called me this morning he said the screw down was shot and it should be replaced, a genuine Eterna SDC is 90 bucks and a movement overhaul is 125. SO a total about $210 to make it like new. I would have about $350 in to it. I know these watches are becoming more popular, I'm not sure what exactly one of these watches are worh all fixed up. I need some opinions should I go ahead and spend the money to have it fixed up? thanks Joe

Help me see the AP light
I've been away from these forum's for awhile , and only just started getting back into them.This week I picked up patek a/c and sub c lv.I just come back from long holiday where I just took my g shock and when came back I wasnt feeling the AP magic anymore.At moment I have the 15400ST and Bumble Bee .I'm thinking the sub lv takes care of my colourful fetish so do I need the bee anymore as well i not looking at growing my watch collection size wise.Also although not that old I find myself prefering watches witch are no bigger then the 40mm mark and not happy with 41mm size of the 15400 anymore . Apart from the my AP's I only have Pam 233 bigger then 40mm now.I very close to selling off both my AP's and think the only watch that may keep with an AP now is 15202 jumbo.You comments are welcome.thanks
