Una gran sorpresa encontrar una micromarca con esta calidad. Tengo muy poco conociéndola y además que no hay muchos videos en YouTube. Destaca en sus acabados y terminados. Diseño propio, la reseña dice que es italiano. Alineación perfecta en los índices y las manecillas al punto de las 12, cosa que muchas marcas de renombre no tienen. El reloj se siente muy sólido, robusto. Te da la sensación que va durarte toda la vida y que vale mucho más de lo que cuesta. Lo elegí por encima de los relojes de AliExpress del mismo rango de precio y que llevan la misma maquinaria. Excelente lum. Lo recomiendo ampliamente.

Seems to be a great value for the price point
The watch has heft and seems to be of quality materials. I'm not a watch collector but I think the watch looks fantastic.

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
Hi there,
Thank you for sharing your feedback with us! We’re glad to hear that the lume is holding up well for your work environment and that it’s been reliable in confined spaces. We also appreciate your thoughts on the bezel and performance. It’s great to know that it’s keeping time well after a month of use. We understand your wish for lume on the bezel and will take that into consideration for future designs.
Thanks again for your detailed review, and we’re happy to be part of your daily work routine.
Best Regards,

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!
