## Description

Seiko 4R36 Automatic Stainless Steel Casing Hardlex Mineral Glass Screw-in Back 100 Meter Water Resistant Grey Dial

Review: Got this after i was disappointed with the snxs79 and man… I love this watch! Hacking is great because seikos aren’t the most accurate and I like to sync my watches to the second, so while it gains about 5 seconds per day, I just stop the watch for a few seconds in the morning and I’m satisfied. I’ve got a small wrist, somewhere around 6.25-6.5” and this fits like a dream. No awkward floating, no overhang. Surprisingly thin for a mechanical watch. The bracelet is still folded links, but probably the best attempt at folded links i’ve seen, split pins to adjust this time around and honestly the bracelet is okay, it fits nicely and if you can tolerate a bit of a jingle, it’s fine. There’s some good aftermarket bracelets like Uncle straps and Strapcode which I will probably get soon. There’s dial is beautiful and changes shades in lighting, I often catch myself just staring at it. Great lume for low light legibility! Can’t say it’s much louder than the older seiko movements if at all but it’s not any quieter. If you’re looking for your first mechanical watch, or just a watch that combines the diver and dress watch look without being massive, this is the watch you want!
Review: Além de muito bonito, o produto chegou bem mais cedo do que o previsto e intacto. Recomendo!!
