Martin from the Philippines requested me to post a comparison between the SBDX011 and the 6159-7010. This is what he wrote to me:
Read your post on the 6159-7010, lucky guy that you got this watch. Hope you can make a comparison between your two tunas SBDX011 and the 6159. By the way, can you tell me how much you pay for the 6159?(if you don’t mind) I am now saving for the SBDX011 and is also thinking of getting the 6159 instead of SBDX011.
So here they are, the 6159-7010 from 1975 and the SBDX011 from 2009.
