Heimdallr Sharkey Frog-man AutomaticvsSeiko 5KX

Heimdallr Sharkey Frog-man Automatic Watches are praised for their cool aesthetic and good case finishing, with some owners noting superior bracelets and solid end links. The bezel action receives mixed feedback, described as both good and very stiff, with one owner reporting a misaligned bezel. Accuracy varies, with one watch running at +6 seconds per day and another experiencing movement stoppages. One owner noted the watch features 200-meter water resistance, which passed testing, and another expressed dissatisfaction with "ocean monster" text on the dial that was not present in advertised photos. On balance, owners find the Heimdallr Sharkey Frog-man Automatic Watches to be a cool and well-finished piece, though some specific examples have exhibited movement issues or cosmetic discrepancies.

Owners widely praise the Seiko 5KX for its strong lume and value, with many reporting accuracy within +/-5 to 10 seconds per day, though some experience +/-1 second. The 42.5mm case is noted to wear smaller, and the watch offers a comfortable feel for many. Some owners are split on the bracelet quality, with opinions ranging from "cheaper side" with hollow links to "flimsy-feeling" jubilee. A few quality control issues have been reported, including a failed bezel clickspring and misaligned components. The Seiko 5KX is seen by some as a worthy successor to the original SKX, offering an upgraded movement with hacking and hand-winding capabilities, though others lament the loss of ISO certification and a screw-down crown. Overall, owners rate the Seiko 5KX highly for its excellent lume and value proposition, making it a popular choice for everyday wear.
