Hello,

I am wondering if this is a ultraman chrono hand.

I have attached a spear hand as reference

 

Thanks this was helpful. I have attached the measurements

 

Looks like a Mark II or Radial hand from length given.

 

Are you sure looks closer to 18.8 then 18

 

Looks shorter than 18.5 to me. In the photo, the hand should be a touch further back on the ruler.

 

It is not an Ultraman hand. 100%

Most likely to be a Seamaster chrono hand.

 

Too much uncertainty in the measurement process. Calipers required

(but even with the noise, still - doesn't look like it fits the ultraman criteria )

 

Apologies for resurrecting an old thread, but I've recently been trying to work out the dimensions of the orange chrono hand for the speedmaster Japan racing (3570.40). I've seen the above table from multiple sources, but I've never seen the 3570.40 reference added in!

If anyone could advise about the hand dimensions for this model (even just total length or 'A') it would be greatly appreciated!

 

For accuracy have someone with a vernier caliper take the measurements. Parallax is in play here.
