I knew about the existence of this watch from 24watches.info, excellent site by Andre Stikkers. I bought it last November from eBay. I think I was the only bidder, because the starting price was not low – €40. And I wasn’t sure that it was smart from my side to spend so much for this small used quartz watch.
This picture is from 24watches.info
The watch came in a bad shape. It wasn’t coming from the drawer. From the positive side, heavy usage shows, that this watch is really wearable and useful.
Especially the leather strap needed cleaning. But as it was obviously the original strap, I did it pleasantly.
I hate snap backs. I’m an old grumpy man and my eyesight and hands are not good enough for precision surgery. And with some snap backs it is, I don’t know why, that to open it is difficult, to press it back is even more difficult. So it was with zer0/24 too. Stupid name, btw. I don’t like these plays with capital and lowercase letters, and numbers. (Grumpy…)
After opening the case I learned something on quartz movements. First question – which type of movement is inside? With Ronda movements it’s easy to determine, but you have to have magnifier. Every Ronda movement has his type number pressed (very tiny), plus additionally how many jewels it has (usually 1 or 4) and is it made in Switzerland or somewhere else using Swiss parts. On this picture red arrow is pointing to the Ronda’s common place for model numbers.
OK, in this case it is Ronda 751.24. The Ronda database record shows, that this movement comes in two versions:
- Swiss Made / 4 jewels / gold plated
- Swiss Parts / 1 jewel / nickel plated.
Good – we have Swiss Made movement inside. Ahem, maybe the price wasn’t too high?
The next question was – is the movement working? When you don’t have seconds hand, it is not so easy to say. I didn’t knew, that two hand quartz movements are ticking only once in 10 seconds. These watches are silent. Only time-to-time you hear a barely audible tick.
Everything was OK and I changed the battery, to be sure. BTW, with this extra low consumption movement the expected battery life is 7 years!
The case is more or less OK, with some usage marks, and the caseback too. Inside caseback is pressed “Hong Kong Case”. Aha, not everything is Swiss Made! The crown, for sure not from stainless steel, is in worst condition. Operating with crown and stem is the weakest point with this watch. It is difficult to pull out the crown, and again, it is even more difficult to push it all the way back.
The dial is very easy to read. There are no minute markers at all, and the hour numbers are small, but I like this dial. It has style. And this common style ties dial, case, strap and buckle into one unity.
On missing minute markers – if you don’t have seconds hand, then it’s not a problem.
I’m not complaining anymore, that the price was too high. I got small, nice, stylish Swiss Made 24h quartz watch, with next battery change after 7 years. And as an extra bonus – I learned something about quartz movements.
