Was disappointed that he only brought a modified oil filled watch to 5km underwater. Would have been interesting if he’d have strapped a stock watch next to it so we could see when it would break.

- homebrewer 2y agoA very similar model (A158 — they differ only in the bracelet) breaks at 200 m: https://youtu.be/G3iMkeF8qmA https://youtu.be/G3iMkeF8qmA https://youtu.be/sep5Tw-55yw https://youtu.be/sep5Tw-55yw The timekeeping mechanism keeps working fine, though, it's only the display that's busted.
- dnisbet 2y agoYep would have loved more on when the watch (unmodified) would actually break and also how you would fill it with oil? There can't be much space inside, at what point does the viscosity of the oil matter? how do you know you've got all the air out?
- aidenn0 2y agoI'm assuming they are using mineral oil; I've not filled a watch with mineral oil, but I have worked with it. Mineral oil is not particularly viscous; some gentle tapping is probably enough to get all the bubbles out. Here's a video of a PC immersed in mineral oil with an aquarium bubbler and you can see the bubbles rise fairly quickly: https://www.youtube.com/watch?v=tUBvWXH1hLs&t=110s https://www.youtube.com/watch?v=tUBvWXH1hLs&t=110s
