Casio AQ-305 Ana-Digi Watch (Module 388) Recase

 Casio AQ-305 Ana-Digi Watch (Module 388)  Recase Hello fellow Casio lovers from around the World. I hope you are all well. In this post I will be recasing a Casio AQ-305 into a better case and strap. I have owned the better case and strap for a number of years and over that time I have bought a number of donor AQ-305's that either fell apart during the recasing procedure or didn't work when I received them. Over that time I have been patiently waiting for a resonably priced AQ-305 to pop up on EBay and eventually I found one last week. I bought the watch for £6.34 and the watch arrived on Tuesday 27/10/2026 and although the watch was well worn, scratched and the gold worn away in places, it worked perfectly. The watch that was receiving the new module (the inside's) was in very good condition. It wasn't perfect but it was of a decent quality and you could easily wear it as a dress watch. So, now that I had the new donor watch and the recipient case and strap, I got to ...

Casio AB-500 Data Bank Watch Battery Change (Module 386)

Casio AB-500 Data Bank Watch Battery Change  (Module 386) Hello fellow Casio enthusiasts from around the World, I hope you are all well. In this post I will be changing the battery in the Casio AB-500 Tele Memo/Data bank watch.  The battery in this watch has not been changed since January 2024 so it is due a new battery. The battery I will be using is a    type 371 silver oxide battery. I am using a silver oxide battery as they are less likely to leak when the battery nears it's end of life. I have been changing all the batteries in my watches to silver oxide as I had previously been using the cheaper alkaline batteries which have a tendancy to leak near the end of their life and that is something I would like to avoid. Leaking batteries can destroy watches and stop them from working. The battery cost me £4.95 which is quite expensive for a watch battery, but it has a less likely chance to leak and I'd rather go with this option. As you can see, the display is faint ...

Casio MQA-100G Battery Change (Module 333)

 Casio MQA-100G Battery Change    (Module 333) Hello fellow Casio enthusiasts from around the World, I hope you are all well. In this post I am going to change the battery in my MQA-100G. The watch had been running well (for over 3 years), until I noticed that the second hand had stopped running and the LCD section had become very faint leading me into a panic to change the battery. I had presumed (wrongly as it happened) that I had a spare battery but I couldn't remember which type it took so I checked an old post to see if I had mentioned it there, but I never mentioned it nor took a picture of the new battery. So that led me to open the watch up to see what type of battery the watch needed. Let me begin... The picture above shows the LCD section is very dim. The second hand has also stopped moving, leading me into panic mode to change the battery. I say panic mode because if the battery starts to leak (and it would have, which I will reveal later in this post) it ...

Casio AB-200 Data Bank Watch Battery Change (Module 321)

Casio AB-200 Data Bank Watch Battery Change   (Module 321)  Hello Casio lovers from around the world, I hope you are well. As the title suggests, I will yet again be replacing the battery in the AB-200. To be fair, for an old watch it doesn't eat through batteries. It has actually been three years since I last changed the battery in this watch so I'm quiet happy with it's battery usage. To be honest though I did use a decent battery (Duracell) in the watch the last time I changed it, so I thought I would use the same battery again.  The watch uses a LR1130 type cell, so I bought the Duracell brand and it cost £3.90. Let me begin... As you can see in the picture above, the LCD module is still keeping time, but the hands have stopped moving so it's time to change the battery. First on all I placed the watch face down on a soft towel so the face didn't pick up any scratches... With the new battery at hand it was time to start the replacement. My first job was to remove...

Casio AQ-321 Ana Digi Watch (Module 309)

 Casio AQ-321 Ana Digi Watch (Module 309) 18/10/2023 Hello fellow Casio Watch enthusiasts from around the World. I hope you are all well. In this post, I will be showing you my old, battered, bent and scratched Casio AQ-321. The watch also suffers (as many of these watches do) with an inaccuracy of the mechanical hands. The problem is, the mechanical hands run about 2 seconds a day slower than the LCD part. It may not seem a lot, but over time (yes obviously) the gap increases constantly. However, that doe's not bother me as I love this little watch. I say little as it is quite a small piece even on my small wrist. I would say about the size of a Casio F-91W only a lot thicker and heavier.  Ana-Digi (analogue & digital display) watches and their history. I have been a lover of the Ana-Digi watches since their release in the 1980's, especially the Casio versions. All the major watch manufacturers had an Ana-Digi watch in their collections such as Seiko, Limit International,...
