Sellita does have hand wound versions that are slimmer (SW510). Maen uses this movement in their chronographs and they come in at 13.4mm including the front and back crystal.

Spring drive is a completely different animal. In most quartz movements the second hand stops in order to save battery life.

Some high frequency quartz movements have a more mechanical tick 8-10 movements per second. I think the 9F does this. Some Bulova Precisionist movements do too. In general these have much shorter battery life specs (around 3 years) and have a larger battery. Average quartz movements will have 5-7. I've seen digital quartz as high as 11 years but there are no moving parts there.

What is super interesting is that almost every Casio I have seen hits all of the markers bang on. Even my Marathon with a high accuracy high torque ETA movement tends to drift. I don't know what secret sauce Casio has but it is pretty amazing.

I'd accept 3 year battery life (vs 5+) for a sweeping second hand on a quartz. Btw, I had a quartz TAG and batteries never lasted more than 4-5 years. I had them replaced by TAG which cost arm and a leg. On my Bulova I change mysef, costs me about less than £1 per battery change

If folk want the ticking look of a quartz movement, maybe CW could release…

A dead-beat seconds automatic.

I haven't been able to discern any difference in design or component quality between the quartz C63 Valour & the other CW mechanical watches in my collection. The sapphire crystal, the 'Lightcatcher' case & applied numbers & logo are all of the same quality as the automatic models. The only difference is the quartz movement which with the solid case back goes unseen. Even by quartz accuracy standards, the quartz movement in the C63 Valour is an extremely accurate Chronometer & came with a COSC certificate to prove it. As for the "ticking look of a quartz movement", that perception is muted with the use of a small seconds rather than a large second hand. The only time that you will notice the quartz ticking movement is when the secondhand sweep is engaged with the stopwatch function. And which has been noted, it would be possible for Christopher Ward to produce a thinner Chronograph than in the past by using a Sellita (SW510) movement if they do it as a hand wound.

Quartz are tested to a different standard too. Including temperature and humidity.

From the COSC website:

I was always anti-quartz, but I've really come around to the idea now that I have so many dead autos in my box.

There are some folks on here who own Citizen "The Citizen" Chronomasters that might disagree with you about nice watches not being quartz

I'm one of them. A fantastic watch with an extremely accurate solar quartz movement (+/- 5s/yr). I really love the watch. The finish is amazing (Grand Seiko standard), the dial stunning with the Wishi paper used to create an interesting effect and it comes with a perpetual calendar.

I am certainly not averse to quartz movements and am enjoying the C63 Valour.

@albionphoto Not to mention the Citizen caliber 0100 +- 1 sec per year

I'm another... Tosa Washi Navy in my case

I like the look of the peregrine c4. As mentioned quartz is a convenient movement. I don’t wear my automatic to work so have to wind it each time I use it, and then it’s 4 seconds/day fast.

I'm among those who like the convenience of quartz and especially solar watches, but I don't need another quartz chronograph.

Absolutely this. A sweeping hand looks so much better. I wonder though whether we don’t see sweeping quartz watches as it would start taking sales away from automatics.
