A rattling sound, noted by some owners, is considered normal for the NH35 movement and is deemed acceptable given the low price point. Overall, owners rate the Boderry SEATURTLE.OCEAN - Automatic Diver Watch (NH35 movement) highly for its impressive feature set and design at its price point.
Owners widely praise the Seiko Prospex Sea 1965 Heritage Diver's Watch for its refined engineering, comfortable 40mm case, and improved 300m water resistance. The watch is noted for its better build quality and finishing compared to some alternatives, featuring a mix of polished and brushed surfaces, with specific callouts for the jewel-toned teal dial with a rippling-water pattern. Some owners consider the price fair, while others suggest it is too high. Accuracy figures vary, with some owners reporting their 6R55 movement performs well within +/- 10 seconds per day, while others note theirs runs slow or have concerns about QC for the price. The bracelet, while improved, lacks modern features like quick-release or extensive micro-adjustments.
