I noticed this difference on my watches also, but it is a result that the bigger teeth are on the 18k and the smaller ones are on the 21.6k movement. the balace wheel looks a little bigger, maybe its a low beat swiss?
took again the 50mm lens inverted and had a look to my watches:
the date of the 3717:
the hands of my 183h:
the dial of my 177h:
and some shots of the 6497 high beat:
fake!! dark canon pins on the sub dials...
triangle @ 12 not big enogh.
btw: minute counter not reset 2 zero...
german daywheel - I know it can be ordered by the factory but it's not common...
lug size is 21mm - not very common...
there are two versions of the kevlar - the old one is textile and starts to fray out the new one ist rubber with texture. I had the older one - unfortunately it was too long for me so I sold it again...
kevlar on ebay I know this is for 20mm but I've bought it in 21mm, I think they have them from time to time in 21mm also
3717 and bracelet from trusty:
kevlar strap from the watch boys on ebay:
a leather strap from the watchsmith around the corner:
gen chronoswiss gator from ebay:
and my favorite beside the bracelet - my velcro skinny from gasgasbones.com:
according to the relatively deep recessed subdials it seems to be the v1. but that's really hard to tell. the AR in the first pics doesn't look better than the standard on the V1 but the last one looks like V2 AR. I don't like the V2 dial because it screems rep in the dark and the different colors on the dial and on the hands looks cheap. but anyway - it looks good on the pics
