With a wide variety of variations, it is very popular as a reverse import watch. Also makes a great gift Review: Ordered the watch yesterday , arrived today. Well packed , desertcart US should learn from CW Watch on this. Watch was brand new, with all tags. Review: The size of the Seiko modding community speaks volumes about the brand’s value at this price point. The SNKP21J1, with its distinctive Arabic dial, stands out both in style and uniqueness. While the movement is somewhat outdated (hand-winding would be a welcome feature), the piece performs perfectly for everyday use. For this price. I don’t know of another brand producing automatics of this caliber. The bracelet is the only notable downside—its rattly, inexpensive feel is major detractor (I returned the SNK063J5 on these grounds. The lug width prevented easily swapping the bracelet. I would have had to swap the case as well). I replaced the bracelet with a black cordura strap, and I’m very pleased with the improvement. I think the watch fits my wrist perfectly. In the future, I might consider upgrading the hardlex to a double dome sapphire (if the CT078 is compatible) and swapping the 7S26 movement for an NH36, but for now, I’m thoroughly satisfied. ## Features - (Approx.)
