Case thickness - Seiko Vs. Citizen

In a prior post about my moving from #seiko to #citizen watches, I cited case thickness was one of the reasons. I decided to photograph a Citizen dive watch I own (NB6021) that has a #miyota9015 movement with the #sanmartin SN0036-G-B that has a #nh35 movement.

The Citizen's case thickness is 12mm while the San Martin's is 13.8mm. That 1.8mm can make a difference not only in terms of weight but also if you're out and about when wearing a watch with a dress or long sleeved shirt.

It's unfortunate Seiko hasn't tried to innovate so their cades aren't so thick and, as near as I can tell, their movements are a factor.

Both movements are not comparable, the NH35 equivalent in Miyota is a 8xxx series. The 9xxx is twice as expensive as the NH35.

The equivalent of the 9xxx series would be a Seiko 6L movement, but they are not as common. I agree with you Seiko could do better using that 6L movement more often.

I have two Miyota 9x, one in a Citizen and the other in a Wise diver. They are great in thinness and also 28800 bph and accuracy. It's great Miyota is offering this movements so microbrands can use them at competitive prices like their GMT.

Also, for what it's worth, you're comparing case sizes, but the case is not a Seiko product, it's a San Martin. (But also wear what you want, I don't have any skin in this game)

I've owned Seiko automatic watches and they are thicker than Citizen watches with Miyotas.

Yes, the NH35 is 1.4mm thicker than the 9015, the 6L35 is thinner than the 9015. So that is the base the manufacturer starts with, then the case back, glass, bezel, all that adds up,depending on their design and purpose.

Seiko should do something to their movements so they don't result in thick cases. It's annoying that they haven't, in my view.
