IMHO
I also prefer the date function. Tear coupons sign documents everything look at your wrist, much easier than digging out the handphone.
As for the chronograph function, its really hardly used. Thats also one reason I sold my daytona. I probably wont be getting any watches with chrono functions again too.
I'm tending more towards the exp 1. It appeals to me more being a watch u can wear casual and sporty - just swap between strap and bracelet.
As for the vacheron, u can try the MBS boutique.
The ocbc dickson promotion I guess they wun give u any discount on even the first piece...?
imo, the watch one wears projects the mood/image one is in/wishes to share.
for eg, daytonas or any chronographs with tachymeter scale associates itself with racing, and if i'm behind the wheel of an aventador, 458 spider, sl63 amg, porsche 911, bmw m6, audi r8, lexus lfa, nissan gtr, etc, wearing an appropriate chrono keeps with mood and spirit of the moment (especially if there're red hands on all the subdials and central seconds hand!

).
a vintage style/inspired watch identifies the owner as being one whose is enamoured by the period/activities which produced those designs. eg. wwII german b-uhr pilot observation watches, vintage/military diving watches from blancpain, panerai, etc, jlc reverso that captures the spirit of art deco period of the 20s/30s, a vulcain cricket/jlc memovox mechanical alarm/universal tri-compax/tissot visodate/hamilton intra-matic that captures the spirit of the 50s/60s when men wear hats and women wear gloves a la breakfast at tiffany's (when men were men and women wear skirts & aprons & stay in the kitchen), heuer autavia/tudor monte carlo/heuer monaco/rolex daytona harkens to the heady racing days of late 60s/early 70s when guts count for more than safety, ap ro/pp nautilus redefining the luxury steel watch in the 70s, etc.
a flightmaster/pilot/aviator watch with a rotatable sliderule conversion tables on the rehaut/chapter ring/bezel are either for real pilots, wannabes or screams GEEK!
a luxury diver projects an image of toughness, adventure, daring-do and ability to function under pressure.
a solid gold watch projects success, having arrived & makes a strong statement about the business acumen of the owner.
a diamond studded watch screams "i'm wearing jewellery that happens to tell the time (unless even that is obscured by a diamond filled dial that's so dazzling that it blinds the eyes ... so so bling it on! look at my owner!"
a slim, solid gold (be it yellow, rose or white) dress watch on a leather strap projects an elegant, sophisticated & cultured image of a gentleman with sober taste and finess.
a tourbillion, minute repeater, moonphase, perpetual calender, rattrapante chronograph with/without open workings and a generous sapphire crystal exhibition caseback just says: "i'm the king of the world!"
