    Using WD-40 on watches?

    I just got a brand new Fortis Flieger. The screw down crown feels a bit "rough" when screw/unscrew it. Is it okay to use WD-40 on the crew to remove the "roughness"?

    Is WD-40 okay for watches? Will it kill or eat through the water proof seals of the watch? Especially at the crown? Some of the bezels on my diving watches feel a bit tight also - I was thinking of using WD-40 on them to make them turn a bit smoother (not going to flood the watch with it, just a moderate amount).

    So whats the consensus on WD-40? Will it kill watches?

    In addition to using silicon grease, you can also use a silicone spray lubricant. It is odorless and safe for seals.

    There's a reason WD-40 is known as "the gunsmith's friend," and it's not because its good for guns - it gums up the works, sooner or later. I would not put it near a watch.

    I´d do nothing at all. What most of the screw down crowns have in common is that a frequent use of the crown will cause smooth operation on the long run.

    WD40 is crap as a lubricant. Just attracts dirt and grime and dust.

    And for christsakes dont squirt stuff into your watch.

    What I do for rough feeling screw in crowns is run some floss (yep, for your teeth/gums) in the threads, it works wonders and really makes a rough, gritty feeling crown to perfectly smooth.

    WD 40 will attract dirt & fluff and depending on the materiel used may affect seals. It's great for unseizing corroded nuts & bolts.

    I've heard that sticky or crunchy crowns and bezels become smoother over time, so you might want to wait awhile and see what happens. If you still need to, I think the above poster's recommendation of a silicon lubricant is a good one.

    WD-40 is a petroleum based lubricant and I'm guessing it's too "heavy" for use on a watch.
