Quartz Omega?

They’re fine, but the value isn’t there. The quartz omega uses isn’t anything special. The only nice feature is the independently adjustable hour hand. Other than that, they’re mostly fairly expensive and nice looking watches. I would have no issue buying a preowned one as the movement is unlikely to fail, but it would have to be a lot of money off!

Absolutely beautiful, im looking at a late 90’s aquaterra at the moment

Looks like im buying one lol, found one from 39mm from 97 with papers that looks like a great deal

Here's my early Quartz Aqua Terra (crap camera on old phone, sorry)

Got it from eBay a couple of years ago, paid £1300 for it. Highly recommended.

Its been faultless, keeps great time as you'd expect & is obviously very versatile and tough.

Go for it 😁👍🏻

Thats the exact watch im looking at now, just wary on authenticity but it does come with box and papers so thats going for it

Had mine since 2002 a few battery changes later and it's still probably my most worn independent hour hand is great for travelling, needs very little maintance I can change a battery so no issues it could do with a proper service and a new crystal but I will wait until one of the capacitor goes. Would not hesitate to get another one. As a grab and go GADA they are pretty un matched.

Cant recommend it highly enough mate.

I own a couple: a Seamaster 120m from 1993 and a Seamaster Professional from 1998. Both are still running fine today with no maintenance other than a battery change.

Omega's quartz movements are, indeed, just ETA movements with fancy decoration, but the base ETA movement is considerably more complex than what you'd find in a $10 Walmart watch. It uses inhibition compensation to precisely tune the timing (every 60 seconds), a short pulse width (< 8 ms) to minimize battery consumption, and asservissement to compensate for mechanical wear.

Love mine! One of my favorite watches and I have a box full of automatic Omegas

I’d love to know more honestly, that was my biggest apprehension with the quartz omega thats this old like the original black dial 90’s Aqua Terra, As much as i love the look and feel of the watch I want to make sure my money is being well spent, i could more than likely get a hold of a coaxial one for about 1,000 more but if I can avoid spending that much extra thats always a plus.

I'm not exactly sure what more you want to know 😕

If you're asking about quartz technology, the Omega caliber 1538 used in these watches is pretty good, especially for its time, but it's certainly not as advanced as you'd find, for example, in today's top-of-the-line Citizen.

As to the specific features of the 1538 (or, equivalently, the ETA 255.461 on which it is based), here's my attempt at an explanation:

Inhibition Compensation: The natural vibration frequency of quartz depends on how the crystal is cut. In cheaper watches, that's the extent of the timing regulation: cut the crystal so as to get a desired vibration frequency and base the movement timing on the assumption that you've cut the crystal correctly. The challenge is cutting precisely enough to get that exact frequency. The 1538 takes a more sophisticated approach. The crystal is cut so that the natural frequency is a bit faster than desired, generally around 4 seconds/day too fast. But it doesn't have to be super precise. Once a crystal is installed in the movement, the actual crystal frequency is then precisely measured for that movement in the factory. The factory then programs each specific movement with a compensation factor to account for actual frequency of its crystal. The programming causes the watch to slow down (inhibit) periodically; in the case of the 1538, inhibition happens every 60 seconds. So if the crystal is cut at 4 s/d too fast, the second hand will advance 59 times every 0.9999537... seconds and then one time after 1.00273896... seconds. The result is a movement whose timing is precisely matched to the crystal installed in it.

Pulse Width: When the movement does engage the stepper motor to advance the second hand, it doesn't do so for an entire second. Rather, the movement turns on the motor for a brief period within each second. The pulse period for the 1538 is about 7.8 millseconds. For the rest of the period (i.e. 992.2 ms), there is no force applied to the motor. This is the main reason that quartz movements need very little service. They are only applying force to the gears for about 0.8 % of the time. Compare that to a mechanical movement, which is exerting force on the gears 100.0 % of the time. It's not quite this simple, but if you consider that a mechanical movement needs service every 5 years, then the 1538 quartz movement would take 641 years to experience the same amount of wear. This is also why modern quartz movements are so parsimonious in their battery consumption: they're not really using any power at all 99.2 % of the time.

Asservissement: Cheap quartz movements simply energize the stepper motor every second and just assume everything works. As you might have guessed, the 1538 is more sophisticated. Not only does it energize the stepper motor, but it also senses the second hand vibration. So it can tell if the hand actually moved like it was supposed to. It uses these measurements to tweak how the pulse is applied to the motor. The 7.8 millisecond stepper motor pulse is not a constant, uniform application. Rather, the movement rapidly switches the motor on and off during that 7.8 millisecond interval. Normally the motor is on for about half the time (i.e. 3.9 ms) and off for about half the time (also 3.9 ms). As long as the hand is moving, everything is fine. But if something (e.g. a speck of dust in one of the gears) impedes the hand so that it doesn't advance correctly, the movement will detect that from the lack of vibration. In the next pulse, it will increase the percentage of time that the motor is on. So it may, for example, turn the motor on for 5 ms and off for 2.8 ms. (Again, these are rapid on-off switches during the 7.8ms.) This has the effect of applying more power to the motor, kind of like pushing down on the accelerator when you're driving up a hill. If that still doesn't advance the second hand, the movement will increase the on percentage even further. It will keep doing that until it suceeds in getting the hand to advance, and then it will back off to return to the half on / half off duty cycle. Obviously, there are limits, but this process can usually allow the movement to deal with any minor mechanical issues. In can certainly cope with imperfections caused by our hypothetical dust speck. The successful motion will also likely dislodge that dust speck so the movement won't have to deal with it next time around.

I like mechanical movements as much as any watch geek, and I own more mechanical watches than quartz watches, but I think quartz technology is pretty cool as well. (And don't get me started on the absolutely bonkers stuff that Grand Seiko and Citizen do in their super high end quartz movements.)

I have these two. They serve me well!! Very low maintenance, highly accurate and less expensive servicing costs compared to the automatics and the co-axials. The jumping hour hand feature is really handy for travel and DST (Daylight Savings Time) without stopping the watch. I got these both for less than 2 grand each. For an OMEGA, these are really great extra points

I got this today. Absolutely love it.

Thats goegeous thats exactly what i’m looking for

I tjink quartz is pretty safe. Owned a vintage Omega Quartz for a while, had it serviced, sold it, asked to buy it back and got DENIED (because it's good)

Its stunning in real life mate. You won't be disappointed

Almost bought a manual 2254.50, but went for the quartz 2264.50 instead - love this watch. Comfortable bracelet, but great on a NATO.
