lume: so far so good… as a heavy machinery mechanic I need consistent/reliable bright lume when working in confined spaces. no complaints thus far.

bezel: not bad, could be better… does its job, keeps track of how long I’m working on specific tasks. however I wish there was lume on bezel.

performance: -3 seconds after my 1st month with this as my “work watch”. not bad at all.

random observations: heaviest watch I own, art on dial looks cheap but you get what you pay for, really wish bezel had lume, still a good tool especially for blue collar work

Best watch for the money on Amazon!

I've been wearing this watch consistently for a month set to -5 sec/ day, and it hasn't lost or gained much time. The case is somewhat chunky so if you don't like that this isn't the watch for you. This watch is also pretty heavy compared to my other autos. It will definitely resist water, to what depth I'm not sure, I'd like to confirm it's actually 500m resistant but I don't have the facilities to test. The bezel is unidirectional and makes a very audible clicking sound, and it won't move on it's own. The strap is kind of on the smaller side for a watch so thick, I've got a ~6 ⅝” wrist and there's only maybe 2 ½" of overlapping strap. I don't currently own a case back opener to confirm if this is a genuine Miyota movement or a Chinese knockoff, but the movement has been solid! The dial is very clear, and easy to read. The date is also easy to read without a magnifier on the crystal. The crystal is actually AR coated and has a very slight dome to it. The hands will not jump when setting the time like most autos at this price point, IYKYK. The lume is actually very bright when it's fully charged. I'd say it's on par, in terms of brightness specifically, with Seiko; however it doesn't last as long as Seiko lume, with watches I've tested.

Overall, for 125 bucks shipped I'm very impressed with this watch. I wish they had more designs and colors because I'd be willing to buy at this price point again, or even higher with higher quality parts! Don't sleep on this watch if you're considering it!
