laskos Posted January 29, 2010 Report Share Posted January 29, 2010 Hello guys! I have a rep rolex submariner and it goes about 10 sec in front per day. I want to open the caseback to adjust the mechanism (eta). What tool do i need? Any link to buy it? Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted January 29, 2010 Report Share Posted January 29, 2010 Typically, you need a specific wrench to open it... But there are other tips and tricks as well, like using some duct taped rolled sticky side out or using rubber gloves to gain leverage. If you're strong enough (like Lanikai), you can simply use your fingers To get the caseback tightened sufficiently, I do suggest the proper tool for threading it back on. BTW, +10 sec per day is not terrible... Quote Link to comment Share on other sites More sharing options...
lanikai Posted January 29, 2010 Report Share Posted January 29, 2010 You can use duct tape rolled up into a ball and apply tension not force in the turning of it.. 10 sec. a day is not bad though .. I would leave it be.. the Rolex case back even for a rep can be a little difficult if it's tight.. I use the bergeon tool or a rubber case opener ball6 seconds a day is good so if it ain't broke..is my thinking.. Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted January 29, 2010 Report Share Posted January 29, 2010 A bit of simple regualtion is all you need Quote Link to comment Share on other sites More sharing options...
Jkay Posted January 29, 2010 Report Share Posted January 29, 2010 It could be that the factory never put any oil in the watch, or that it needs a simple adjustment, as you suspect. Did you pay a little or a lot for this watch? Quote Link to comment Share on other sites More sharing options...
prdubis Posted January 30, 2010 Report Share Posted January 30, 2010 Hi there, Btw, anyone knows where to buy caseback openers for Rollies at good price? And Panerai caseback openers too? Thanks! Quote Link to comment Share on other sites More sharing options...
jfreeman420 Posted January 30, 2010 Report Share Posted January 30, 2010 No one mentioned that if you have to ask how to remove the case back, you probably shouldn't do it. Quote Link to comment Share on other sites More sharing options...
offshore Posted January 30, 2010 Report Share Posted January 30, 2010 Hi there, Btw, anyone knows where to buy caseback openers for Rollies at good price? And Panerai caseback openers too? Thanks!

Opens a Rollie caseback in a sec without any kind of effort!!!i got one from O/S and i highly recomend it...especially at this price Oh and BTW 10secs+/day is not that bad Quote Link to comment Share on other sites More sharing options...

Yeh, we reckon these are a pretty versatile little unit. Sometimes you will need to have the case secured to get a result, and there will be times when more specialist tools are required. However these fill a gap, in the fact that they offer the versatility to fit most casebacks (even big Panerai), and they aren't a kings ransom. And yes, I'm with a few of the previous posters...if you don't know how to open a case back, probably you shouldn't until someone shows you how, and don't go "investigating" using a good movement, grab a couple of clunkers and tear them to bits! And finally I have lived with a watch for 5 years at 15 secs/day loss, so I wouldn't be real keen to see damage done- to better that sort of a variation.

laskos Posted January 30, 2010 Author Report Share Posted January 30, 2010 (edited) I think that something that gains 10 secs per day, cant be classified as a watch for my needs... In a week you are gaining above 1 min and this is bad... I read this article: and says that you can adjust your watch to a second precision... I will try the trick with duct tape right now and if i fail will buy the opener tool. I liked and the regulation tricks also... I will let you know the results...

laskos Posted January 30, 2010 Author Report Share Posted January 30, 2010 I failed with duct tape and i am going buy the tool.. I searched the ebay for tools, from hong kong, to get it here in Europe soon and i found this: http://cgi.ebay.co.uk/JAXA-TYPE-WATERPROOF-3-JAW-SCREW-BACK-WATCH-CASE-OPENER_W0QQitemZ370264002947QQcmdZViewItemQQptZUK_Jewellery_Watches_WatchAccessories_SpareParts_SM?hash=item5635745183 Something like this will going to open the oyster caseback of my Rolex??

offshore Posted January 30, 2010 Report Share Posted January 30, 2010 @laskos, Certainly a Jaxa style opener with the correct tips can and will do the job. Unfortunately a lot don't have enough opening to cater for a lot of watch models. In fact we at Watch Bitz offer 2 versions. http://watchbitz.com.au/shop/index.php?_a=viewProd&productId=183 http://watchbitz.com.au/shop/index.php?_a=viewProd&productId=59 These were selected from probably 30 different styles of the same tool we saw and checked recently. One of the big differences is the level of engineering/machining on the adjustment screw threads. Many of these versions allow 1mm+ play which will only finally lead to scratched case backs, and frustration with cheap tools. I know they all look similar, believe me, once they are in your hand,or more importantly hovering over a case back, then quality does matter. Offshore.

In a week you are gaining above 1 min and this is bad... Even if you go and buy a COSC certified chronometre it will still only be guaranteed to run with in -4 and plus 6 seconds a day if you really can live with that then i think you need to look at quartz. We all know that they can be regulated better than that but there is no guarantee it will always be like that, as the oil becomes old it will start to gain time again, it could take a bad knock ect Quote Link to comment Share on other sites More sharing options...

We all know that they can be regulated better than that but there is no guarantee it will always be like that, as the oil becomes old it will start to gain time again, it could take a bad knock ect I will have to agree with Andy here...If you want precision and accuracy then go with the quartz option.On the other hand if you need precision and accuracy with an automatic watch then get a gen Rolex. COSC has set a -4/+6 a day for a reason...so if you think that your rep's gain at +10 is unaceptable then you should go with a quartz or a gen Rolex (ROLEX regulates its watches withint -/+ 1 or 2 secs).Precision and accuracy (at least in the way you want them) do not go along with reps,especially with the unserviced ones BTW if you try to mess with the regulator then you might just end up messing up the beat...be very carefull...

laskos Posted January 30, 2010 Author Report Share Posted January 30, 2010 BTW if you try to mess with the regulator then you might just end up messing up the beat...be very carefull what do you mean?? in this article: all seems very simple: you stop the movement, open the caseback, adjust the regulator with one screwdrive,spray a little silicone oil in the plastic ring of the caseback, close the watch and everything should be ok! Or not?? Quote Link to comment Share on other sites More sharing options...

TeeJay Posted January 30, 2010 Report Share Posted January 30, 2010 To be fair, it is possible to get a rep movement to +0.05 per 24 hours. But. Without proper analysing equipment, it takes a LOT of trial and error, and near constant micro-adjustments to get the correct timing, and it takes a while to 'get a feel' for the kind of minute pressures required to do so. Before I got the hang of regulating a watch, I killed several movements through nothing more than inept clumsiness. I would agree with Andy that if spot on accuracy is essential, then quartz would be best suited for your needs, there are some nice quartz watches available, and, at the end of the day, the most important thing with a watch, is that it meets the needs that you personally have for it. Not what looks good on that guy's wrist, or what the guy in the movie wore, but what is best for you. I really like the 1655 McQueen Explorer II. It looks the business, and who doesn't like Steve McQueen. But. I hardly ever wear it, for the simple reason, that a Submariner, with larger dial markers and a timing bezel, is more useful to me and my needs for a watch. I would have no hesitation in wearing a quartz watch if I needed absolutely bang-on wear-it-and-forget-about-it accuracy, but the fact is I don't need a watch to be that accurate, and, as a counterpoint, I can regulate the movement accurately enough for my needs. It all depends on what is best for you. If you do want to learn how to adjust a mechanical movement, then kudos to you, it is certainly a very rewarding experience Quote Link to comment Share on other sites More sharing options...
laskos Posted February 27, 2010 Author Report Share Posted February 27, 2010 (edited) Hello again guys! Sorry me about my bad english, but i have to report that after 2 openings and adjustments, now i have a watch that is loosing about 4 secs every week!!! when i leave the watch in the night with the dial up. Before regulation was loosing about 70 sec/week when i was leaving the watch with crown up. Amazing result i think!

signumboy Posted February 27, 2010 Report Share Posted February 27, 2010 or you could have set it to -70 seconds every sunday Quote Link to comment Share on other sites More sharing options...

laskos Posted March 1, 2010 Author Report Share Posted March 1, 2010 (edited) Well done I assume you have leaned a little in doing this? Yes i have learn something... That if i had a gen Rolex, it will going to gain 35 secs a week and i will not going to open the caseback to fix it (because its a gen Rolex!) and i will not send it to Rolex service to regulate it, because will going to charge me 250 euros. I think that i have a more precise mechanical watch now, than a lot of gen Rolexes! Edited March 1, 2010 by laskos Quote Link to comment Share on other sites More sharing options...
maxman Posted March 2, 2010 Report Share Posted March 2, 2010 A bit of simple regualtion is all you need I was having a problem with my RW nabucco about nine months ago. Offshore recomended the same advice as Andy. I was a little apperhensive at first but It Indeed worked. The watch was running about 60 sec fast every hour. The watch now runs around +5-7 per day, good advice. Mike Quote Link to comment Share on other sites More sharing options...
