I have been snooping around the forum for quite a while, mainly gleaning info on Seiko divers and drooling over those dream dive watches, but I have just come across something that has prompted me to make my first post.
Now I am not a watch collector although I do love nice dive watches and have two 6309-7290s one of which I have had a go at modding (came with an awful repo dial and hands)
But I do collect vintage diving equipment and while cruising the big auction site I came across a collection of diving instruments for sale and on closer inspection I recognized an aquadive model 50. the photos posted were a little sketchy but I took a punt and made it mine.
what arrived was a very dirty Rotary Aquadive Time-depth model 50. A quick clean with a soft cloth reveled a watch in stunning original condition, it has only one scratch on the case near the crown and some small scratches on the case back that look like they came from sliding around in a draw. The bezel and the crystal are almost flawless, it came on the original skinny plastic strap. the most noticeable thing was the inside of the crystal was fogged up with a greasy layer. Using the guide from the Desk divers site I started to strip it down with the aim to clean the inside of the crystal and pop a battery in it and see if it still goes.
Opening the back revealed a bit of a surprise as there was no old battery in it and the battery strap was broken. did the broken battery strap force the watch into an early retirement which would explain its good condition? the rest of the insides were in top condition, the seals are cracked and hard as expected but the depth gauge still functions, also the second hand is slightly bent down at the tip probably by the same person that broke the battery strap.
So I cleaned the crystal, made a temporary repair of the strap popped a battery in and away it went.
Next on the list is a nice chunky strap maybe mesh, a better, cosmetically repair of the battery strap (ultimately a replacement if possible) and tracking someone down to service the movement.
Now the big question I have is i have not yet seen another model 50 the same. Mine is a Rotary branded Aquadive but the depth display is in feet not meters has this been documented before? all the Rotarys i have seen have been in Meters. It has had the Patent removed (you can just make out the US) i would be interested if anyone has seen one the same.
