This is a good beater watch or use the movement for your 6309 diver. Seiko 5 with full luminous military dial and hands (still glow after exposing to light ;D ). Dial and hands are in great shape, case is in good condition with the typical marks / shallow nicks here and there. The crystal has scratches but more importantly, it looks to me that it has underneath cracks along the 5-7 and 8-10 markers. Double quickset and the crown is at 4 o'clock so it's a direct drop-in movement for your 6309 diver . The movement runs well but service history is unknown. The original bracelet will "probably" fit a 7.5" wrist max. ASKING $50 shipped USPS Priority Mail with Delivery Confirmation anywhere in the United States. I've tons of references and well over 130 verified sold transactions with PayPal. PayPal preferred (as gift PLEASE!!! ;D ). Thank you.
