Casio AD-732 Ana-Digi

It's not often that there is a watch by a brand as large as Casio which seems to be missing from the internet, but today I'm wearing one.

This model is the AD-732 by Casio, and the only link I've found online is to one single online auction. I can't even see any other models in the range with the only other Casio AD- models I found being for keyboards. The watch uses a 789 module, which is also missing from the archive of Casio manuals online, and there is no reference of this module online either. On this basis, I'm guessing that it may be a very rare and unusual model.

The main part of the watch is the analogue display which is a 3 hand dial design. The unusual feature is that there are 5 small LCD windows at the bottom of the dial - 3 round and 2 rectangular. The centre round window is a small LCD dial, and the rectangular windows have items such as the pm marker and fill and empty with the seconds. The remaining 2 small round LCD windows show the modes in use, with the options of time, timer, alarm, and dual time. Modes are switched and used by the two buttons on the case at the 4 and 8 o'clock positions.

The design is like a standard smart sports/divers watch with the watch having a purple rotating bezel with minute markers. The face is in light blue with an unusual design of hour marker at the 3, 9, and 12 o'clock positions. The case is stainless steel with a screw on back and 20 bar water resistance. On the back, it also has the Marlin symbol, but this is the leaping Marlin rather than the swimming Marlin design. The leaping Marlin was used on some of the Casio divers watches (of which I blogged the MD-730 in April) and it isn't the same as the models usually associated with the Casio Marlin range.

Due to the lack of online info, it may suggest a 90s model, but that is just a guess because of the lack of concrete information.

Casio MD-730 - maybe a Marlin?

Today's watch is another Casio, and an intriguing one.

The watch is a Casio MD-730, and is one of the simple Casio Divers watches. The MD series all seem to be divers watches, but there isn't much online about them, although what is there suggests a 90s release. This model, the MD-730, has very few hits online, so I don't know too much about it.

It is a typical 3 hand dial design with day and date at the 3 o'clock position, and a rotating bezel. It is 20 bar water resistant, and has a screw down crown unusually at the 4 o'clock position. Inside is a 709 module which was used in many watches, and is part of a common Casio Analogue multi-module manual.

The intriguing part is what is engraved on the back. The back plate features an engraved picture of a sailfish which is the same as printed on the Marlin watches. This fish is in a slightly different pose than the Marlin logo, so I don't think this is a Marlin model, but it's interesting that is uses the same fish for its logo!

Casio Marlin W-35 LCD

At a first glance, today's watch looks like a normal 80s LCD model. But just above the display, in the top right, is a symbol which makes it a lot more collectable.

The watch is a Casio Marlin watch, and it is the Marlin label that increases it's collectability by a lot. I haven't found out what makes them so special, but there is a lot of discussion and even dedicated forums for the Marlin watches. The Marlin fish, after which the model is named, has a distinctive long body, sharp pointed snout, and large dorsal (back) fin. It is an extremely fast swimmer, and is hunted for sport in tropical regions.

This model was released in 1980 and is the W-35. As a marine model, it has a 50m water resistance, and is a lithium model too. The W-35 is one of the Stainless Steel Marlins, and is Japan made.

It uses a 248 module, which was a very common Casio module in that period. It has the usual modes of alarm, chronograph, and timer. The LCD display is two lines, having a 6 digit time display along the bottom, and day/date along the top. Night use comes from a bulb based light.
