I think certainly one of the most interesting watches I've ever owned, just got this Zenith A3642 octagonal shaped diver!

I believe it's 1970s, and with the original Gay Freres ladder bracelet. For what it is, the prices of these are a steal!

Anyone else out there with one?

 

Congrats! I'm a fan of these old Defys. For sure not to everyone's taste, for me they are wonderful in their own quirkiness. They definitely are nicer in person

 

Also a fan - if you want to collect these, there are lots of dial variations, and there is also the crown-at-4 version to chase down.

I've only noticed that the blue-dial version begins to flake off, exposing the brass.

They stand up well, and they look great on the ladder bracelet.

 

Lovely! One of the best looking 70s watches.

 

Here's my A3643, Fr. 330 back in the day:

 

I love these! Such an interesting and unique design and overall a very well made watch.

I only have an A3651 but would love to add one of these to my collection.

Here is my A3651. Just on the top part of the watch head, there is polishing, straight graining, circular graining, and a sunburst finish.

 

Lovely pieces all, thanks for sharing!

Does anyone know if these bracelets are adjustable with being able to take links off, at all?

Seems like from the construction, no...

Ahhh thanks for sharing, amazing!

 

Indeed, nice they are, but I didn't know they were divers. Where do you take that from ?

 

That case is amazing!!

 

Ahh I think I had read that somewhere due to the 300m water resistance, but thinking again it's probably not a dive watch!

 

In the ad in the OP it says they are “waterproof” to a depth of 1,000ft. However, while they can handle a dive, I doubt they would be classified as a diver since they don’t meet ISO standards. Still, really cool pieces that are engineered to be very capable

 

You could buy one with a Diners Club card for those who remember that

 

Here is a picture of the insides. The movement is shock-protected by a rubber/plastic ring. I guess similar to a Certina DS.

 

great pickup, @guaranteed.rohu

Wear it in great health
