  1. Hi, I am working on two 70's watches (Owix automatic & Polek Automatic) that both claim to be "waterproof". No screw down Crown, so I am aware one shouldn't go diving with them or maybe even swimming. I've seen the same case tube and crown build up on a couple of watches before, such as a Zenith Sporto, and I wonder if there is something I am missing. Like this it feels you couldn't even wash your hands. Should there be a gasket inside the crown? As you can see in the picture I usually find alot of gunk inside the crown, but I have just thought it to be old dirt. Could it be a dissolved gasket? There is no obvious place for a gasket inside the tube, and I've never found one there either in these types of cases. It feels like there should be some more feature for this to be called "waterproof". Anyone with any thoughts about this?
  2. Hi everyone. A bit of a puzzle. I know there's probably a straightforward answer to this... I have a Victorinox Swiss Army Officer's 1884 - 24709. I need to understand... How do I waterproof when the crown is pushed in? It appears to have a flush post crown which the stem screws directly into. However the case tube is also flush with the case. The stem has some wiggle in it when attached as if something is missing. However looking from the inside there doesn't appear to be any evidence of a gasket. Has anyone seen this type of setup, or know what may be amiss? I would prefer to keep the crown if at all possible. Otherwise I would replace the case tube with a generic screw-down crown but that's really a last resort. See attached pics. Thanks! -A
  3. A quick step-by-step tutorial on how to replace the battery on a TAG Heuer Aquaracer. This watch belongs to a good friend, and it is in need of a battery replacement. Step 1: Remove the screw on case back. The tools I am using are a three-pins Jaxa case opener and a case holder. At first, I try to open the case-back just with the watch mounted on the case holder. But the case-back is very tightly screwed on (this is a diver watch with 300m waterproof). In the end, I secure the the case holder on a mounted bench vice to free both of my hands to open the case-back. I also find that using a three-pins opener a lot better than a two-pins, especially for a diver watch. Step 2: Check the battery The quartz movement inside this Aquaracer is a Ronda 6004.B, which uses 373 Silver-Oxide battery (or SR916SW). When I receive the watch, the battery is not fully exhausted. The small-second hand jumps every four seconds (battery-saving mode), though still keeping time it shows that the battery is weak. With battery replacement jobs, I usually receive the watch with a fully exhausted battery. To ensure that the issue is not with the movement, I always test the old battery before replacing it. A quick test on this battery shows that the problem is with the battery. A new battery is around 1.5Volts. Step 3: Grease the seals Before I screw the caseback on, I grease the caseback seal using Seiko silicon greaser (S-916) that comes with an applicator and the crown seal with Seiko greaser (TSF-451). If the seal is no longer in good condition, it is advisable to replace it also. Tip: To grease the seal on the crown, you will need to first remove the stem (or watch winder). Below is an excellent video on how to remove a stem on just about any watch. Step 4: Waterproof test The next step is to waterproof test the watch. Note: I am still saving up to get myself a waterproof tester. Job's done!
