Original Scope Posted March 11, 2012 Report Posted March 11, 2012 Do you think it is possible to fit a gen 7753 with the 7760 bridge in a DW V72 case. Just looking at options.
chiman12 Posted March 12, 2012 Report Posted March 12, 2012 Yes...but there will be no way to secure the movement down. Different clamping heights between the 7753 and V72...but if you can make a special movement tab...
Original Scope Posted March 12, 2012 Author Report Posted March 12, 2012 Thanks ChiMan,I may see what i can come up with.
Original Scope Posted March 12, 2012 Author Report Posted March 12, 2012 So would there be any issues with stem and crono pusher placement?
chiman12 Posted March 12, 2012 Report Posted March 12, 2012 I believe that the stem height won't be an issue as I've tried fitting a V72 into a DW 7750 case once and it align perfectly. The chrono-levers on the 7750 movement are a lot wider than on the V72, so the pusher placement is not an issue. To be on the safe side, why don't you just use a 7750 case? I'm quite positive DW still have those for sale. If he doesn't and you need one, PM me...
Ephry73 Posted March 12, 2012 Report Posted March 12, 2012 The issue I see with the 7750/60 movement in the V72 case is that the reset pusher won't engage the movement lever to reset. I need to play with the length a little to see
chiman12 Posted March 13, 2012 Report Posted March 13, 2012 The pushers for the V72 and the 7750 case are exactly in the same position... DW V72 case on left and 7750 case on right 7750 on top... Only slight variations in the 7750 case...
Ephry73 Posted March 13, 2012 Report Posted March 13, 2012 It literally is like a mm or less of difference. E
Original Scope Posted March 13, 2012 Author Report Posted March 13, 2012 My original plan was to go with a V72 movement but between the price of the movement and service I was thinking a new 7753 would be a little cheaper and rock solid.It will be a little while until I get the movement so just exploring options.Next on my list is gen spring bars and crown and tube.Thanks again Chiman.
Ephry73 Posted March 13, 2012 Report Posted March 13, 2012 Scope, The 7750 route is the most practical, specially if you are going to put some mileage on this one. E
lhooq Posted March 13, 2012 Report Posted March 13, 2012 ChiMan: How hard would it be to convert a V72 DW case so that it would accept a 7750? I bought a small number of V72 cases during the "DW's going out of business" scare, and I'd like to make immediate use of at least one of them!
Original Scope Posted March 13, 2012 Author Report Posted March 13, 2012 I have a bridge coming from Cousins for the conversion and will be on the lookout for a 7753. If it doesn't work on the Daytona I might just order a generic case and dial.Perhaps we can come up with a top movement ring for tabs.
Ephry73 Posted March 15, 2012 Report Posted March 15, 2012 Speaking of pushers and crowns(hate to thread crap) Is it correct to have a 702/3 crown with pump pushers, or were the pushers also changed with the tube/crown service?
freddy333 Posted March 15, 2012 Report Posted March 15, 2012 On 62xx Daytonas, only the Oyster cases (screw-style pushers) had Triplock crowns. Non-Oysters (with pump pushers) all had Twinlock crowns.
Original Scope Posted March 15, 2012 Author Report Posted March 15, 2012 If serviced I would think that if you have a 703 crown that pushers would be changed to screw downs. I always thought that in order to be called a oyster it had to be a screw down pusher.
Original Scope Posted March 15, 2012 Author Report Posted March 15, 2012 Must have been replying at the same time.
freddy333 Posted March 15, 2012 Report Posted March 15, 2012 I always thought that in order to be called a oyster it had to be a screw down pusher. Close. In order to BE an Oyster, a Rolex chronograph must have screw-style pushers (the screws lock the pusher closed, which keeps the owner from accidentally pressing it under water).
Ephry73 Posted March 15, 2012 Report Posted March 15, 2012 Perfect! Thanks guys. I keep looking at pictures and some of the crowns look bigger than 6mm in some of the pump pusher models. E
freddy333 Posted March 15, 2012 Report Posted March 15, 2012 I keep looking at pictures and some of the crowns look bigger than 6mm in some of the pump pusher models. Rep watches often do not get all the details correct. When trying to learn (about gen details), you should check out the watches at your local Authorized Dealer (AD), or, in the case of vintage models, in gen forums.
Ephry73 Posted March 15, 2012 Report Posted March 15, 2012 That's what I mean. There's a picture of a PN 6239 and the crown looks bigger than 6mm more like 7mm but the shape is more like the 700 crown and has the pump pushers. When I get home I'll post it. Thanks Freddy. E
Logan Posted March 16, 2012 Report Posted March 16, 2012 The 7753 needs the date pusher or you'll have a slow set date..
Original Scope Posted March 16, 2012 Author Report Posted March 16, 2012 For the 6263 I will not need the date. I am planning on converting it to a 7760 which is not made anymore.
