This watch is beautiful. I regret not wearing it, I have too many watches and I need to clear some out. I replaced the nylon nato style strap with a complimentary toned leather strap. Haven’t worn other than to try it on. This watch has a mechaquartz movement. The hand sweep is silky smooth. The case size is 39mm. It fit my 7” wrist perfectly. The band size is 20mm for reference. I will be sad to see it go but I have a Hamilton field watch that already fills the void.
