I would actually love this watch (I'll be returning it) but the shank doesn't lock making the watch waterproof. It arrived in a box that had already been hacked when someone set the time and date (albeit to EST) so I can only speculate that whoever did it might have taken off the guard you normally do see behind a new clock stem. Otherwise I would keep the watch if the stem is clogged as it is beautiful despite being thick; I measured it at ll and maybe 0.25mm thick. I mainly wanted it for traveling to places where I will be snorkeling so it will not help me without a mounting shaft. I think I will order a replacement and hope no one opens the watch before I receive it.
