  • The watch repair course and videos section has moved - if you are a Patron via Patreon or a WRT Subscriber, kindly create an account here: https://www.watchrepairlessons.com, if you have not done so already, in order to continue with your access to the Early Access and Ad-Free videos.

    The Patron and Subscribers section in the WatchRepairLessons.com dashboard (direct link) will detail all your subscription details. 

    This will help me consolidate all my videos under one roof rather than maintaining two separate systems, and it will also help clean up WRT a bit.

    If you have any questions please message me, Mark :)

    • Actually that is not true. If the slot is wider there will be no full contact between driver blade and screw, but there will be two shorter points of contact, since these are parallel to the axis of the blade they  not tend to lift the tool, which is good. In addition there will be some friction between the tip of the blade, and the bottom of the slot. As a result, he screw will be driven properly. Compare to a wedge shaped (aka flared) driver. In theory there are always two thin strips of contact, which are as wide as the blade. The down side is that the blade tends to cam out because there the surface asre not paralled are inclined, and there is no friction contact to the bottom. Parallel tip drivers are also somehow common in general mechanic, from small to big sizes. These are usually considered better, and are more expensive.  In the comments of this article https://www.cnccookbook.com/8-brands-to-consider-for-the-worlds-best-screwdriver you can read about paralled, plus JIS and Pozi cross types, which are unknown to many.
    • Send it to replateit.com in Canada. Wonderful work. They know omega. Theyve done dozens for me so far.
    • Glad to be here....
    • Suggest that you post in the correct forum which is "watch repair help" or perhaps "chat about watches", because not everyone reads all sections. You can also ask moderator to move you post.
    • There is no other way. Note well, it is a 600m waterproof watch, these are normally built with as single piece cases, quartz or mechanical.
