The cousin of the 6309, the 6306 is a 150m diver that looks and feels identical to the cushion-cased 6309, but was marketed only in Japan and uses the cal. 6306 movement.
The cal. 6306 movement has 21J and runs at 21,600 bph. It hacks and has a quickset day/date calendar mechanism with a Japanese/English day wheel.
The 6306 divers are much rarer to find than the 6309s because their production years were relatively short and they were Japan-only models that use a 21J hackable movement (compared to the 17J non-hacking movements in the 6309s). Like the 6309, the 6306 diver has a bi-directional non-locking bezel.
The 6306 diver differs from the 6309 in that the cal. 6306 movement has 21J (as supposed to its base caliber 6309's 17J) and it has a Japanese/English day wheel
