Thread: 2021 a year of quartz and accuracy trials

  1. #1

    2021 a year of quartz and accuracy trials

    For a variety of reasons, mostly due to lockdown, I've been wearing my automatics far less frequently. I decided that this year would mostly be a year of quartz, particularly my recently acquired Seiko Arnie. This watch does just about everything I need and wears very comfortably for a larger watch.

    In January, I noticed it kept really excellent time, even for a quartz, but decided that empirical evidence was required. I decided to conduct time trials in February, for it and some other commonly used quartz movements.

    I pitted the Seiko's H851against the 3229 module in my G-Shock DW-5600-E and the E168 in my Citizen BN-0151 diver.

    I set all three to atomic time on the 1st of February and here we are 28 days later. The results are in.

    They all share the same specification of +/-15 seconds a month, within comfortable temperatures.

    The Citizen was +6, the Seiko +4 and the G-Shock +3 after four weeks, which translates to annual figures of:

    Citizen +78s
    Seiko +52s
    G-Shock +39

    So not quite in the HAQ range of Grand Seikos or others, but certainly good enough for everyday use, and all three are great watches. But I do like the idea of the cheapest watch being the most accurate.

    There is something nice about the precision of quartz. You can leave it aside for weeks, and it will still be accurate. I always own at least one quartz. In all, they perhaps get underestimated. Not as exciting as a mechanical design?

    I too have been wearing quartz more since lock down. I track their accuracy on the app twist. (Yes I am sad)
    My Tuna is currently +6.1 seconds since the start of GMT my G10 is -3.7 over the same time period, which is not bad for an old unserviced watch.
    In contrast my kinetic seiko diver is +36 and my JSAR is +46. So even quartz can vary.

    Maybe Iíve been lucky but I have never had to correct a quartz in the 6 months periods between the hour changes. My criterion is more than a minute out.

    Canít beat a quartz for accuracy, particularly when it resets itself against the atomic clock on a daily basis as many Japanese quartz watches do.

    I know it's cheating as the timekeeping isn't strictly happening inside the watch, but it's kind of insane that for £50 you can pick up a multi-band 6 solar G-Shock and literally never worry about it again. Insane value.

    Yes indeed gents, some excellent points. The atomic G-Shocks are still modern marvels to my mind, with my all time favourite being the GW-5000.

    For the non-WIS, they're clearly the best way of telling the time, although smartphones are superceding watches.

    2021 a year of quartz and accuracy trials

    I love my GS 9F quartz and decided to time it few months ago, but itís proving to be really boring.

    Excellent accuracy!

    But you make an interesting point, when does that level of accuracy but lack of interaction become dull?
    I've had a Seiko HAQ with perpetual calendar once and a SBCM023 not HAQ but close, and moved them on in part because once set, that was it.

    Never. I never tire of watching the second hand of my 9F tracking against the BBC pips on the analogue signal, and retaining its 0spy accuracy.

    My lower end Luminox has gained 4 seconds in the two months I've owned it. I will be resetting it for BST of course, but if it wasn't for that it would be about 24 seconds ahead after a year at this rate!

    Just read the OP - that's an idea - I'll do it with my Quartz watches in March and see how things go!

    ETA for my benefit - I set my B-1, my Certina DS-8, my Tissot PRC-20, my Citizen dive watch and my two Sekonda chronos!

    Will be interesting to monitor progress...

    I do miss my quartz watches. Sold 5 of them to put towards getting an Aquis then sold the other one not long after. Bought a GWM5610 recently though and have enjoyed it.

    I've had to reset the time on my Citizen Eco-Drive diver due to the BST change and needing the watch to, wait for it, go diving!

    At 14:54 on 28th March, it was reading -2 seconds against time.is, which seems OK to me, given that 1 of those is probably margin of error anyway.

    I'll update the others on the 1st April, a full month later, as I'm not bothering setting the hour forward on those beforehand.

    My X-33 with 1666C movement is super accurate. Just changed it's battery last week



    So will keep an eye on accuracy. I have a technical manual for the Cal 1666 on how to adjust any drift in accuracy - might be fun.

    Nice to hear. I've also made a note of timings since the end of October, using a program I'd written myself. Most of the results are unremarkable, for example my solar Seiko 'PADI' diver gained 39 seconds in that time. My solar Pulsar field watch gained 17 seconds. My Seiko solar chrono gained 14 seconds. A cheap Casio digital lost 4 seconds, which is pretty good in 5 months.

    My Newmark field watch gained 2 seconds in the 153 days since the 26th October which I think is remarkable.

    But the overall winner was this one:



    I think I bought it for about £80 in a sale somewhere. No bluetooth, no radio controlled timing. But it's gained bang on 1 second in the last 153 days since Oct 26th. I've just set it about half a second slow for BST and if it continues in the same vein, it will be less than a second fast when the clocks go back in October.

    hope you donít mind me asking - what is the Casio model number?

    Not at all, it's a GM-5600B. But the module is the 3229 which is present in a number of other G Shocks.

    I had a Newmark 52 until recently which was also impressive. By contrast my new Seiko Arnie seems to gain at least 15 seconds a month. At this point I only own quartz watches with currently 27 Casioís and a fair spread of different brands - I set them all last night and donít intend to reset any until the clocks change again. From memory my most accurate is the cheapest - a ca-53 calculator watch, I suspect my recently purchased CWC diver will do well and a couple of other Casio Ďcheapiesí will bely their price too. I have noticed that if any of my Ďsolar atomicsí fail to synch they are the most inaccurate of all their g shock brethren. Iíll simply take a look every month or so amd report back!

    So, 1 month on...

    Breitling B-1 = -2 seconds
    Certina DS-8 = +1 second
    Tissot PRC-20 = 0 seconds
    Sekonda chronos = -2 seconds and 0 seconds

    Timed against Time.is.

    Virtually nothing really, impressed by the Tissot (£200ish) and Sekondas (£50/£60ish), though, proves you don't need to spend much to get good quartz accuracy!
