As a possible future owner of this beauty I'd like to have very important data as written here. First of all owners should chime in, while on points 4.-7. Chrono Avenger M1 and on points 6.-7. Chrono Colt Quartz owners too.

Please provide some data (either here or via PM) about the:

1. lug-to-lug size
2. total height incl. crystal (at the center of the watch - have to size personally because there are errors in the official Breitling data at some models, a. o. CSO I.)
3. total weight on Professional II. bracelet
4. regatta cownt-down function: how to start it?
5. does a "normal" chronograph function also exist? (= start at "12" instead of "10")
6. minute hand step: 20", or 30", or?
7. date disc advance: instantly or over a period? If so: how long? Jump: exactly at midnight, or?
8. how do you time the battery change - as there is no end-of-life feature

What are your general impressions about this watch? How is the wearability and looks on the wrist compared to e. g. Super Avenger and CSO I.? (Having a 6.75" wrist the SA looked completely unwearable and comic on my wrist, where it spent cca. 1 minute... I have a CSO I. and it wears very fine with 42 mm size and 17.2mm measured height, 202 g on bracelet.)

Many thanks for every kind input!
Best regards from beautiful Budapest,
