6263 dials according to serial numbers

[JM_FR]

Hey guys,

I am doing some homework on 6263-6265 dials and struggling a bit on the correct periods for each dial variation.

To my knowledge there are 4 variations:

1 - MK1
- No Daytona
- T-Swiss-T at 6
- serial range 2.08-2.8m --> is this correct?
- Pushers: millerighe for the earliest (up to c. 2.2m), then Mk0 2.2-2.8 and Mk1 for 2.8-3.05m


2 - Sigma
- No Daytona
- σT SWISS Tσ at 6 (either large or small)
- serial range: 2.8m-4.x?
- Pushers: MK0 (no line, tight vertical cranges until serial 3.0m 1972) or MK1

3 - Sigma Big Red
- Big Red Daytona
- σT SWISS Tσ at 6 (either large or small)
- serial range: 3.9m-4.2 ? I have also read 5.2-5.5m range
- Pushers?

4 - Big Red
- Big Red Daytona
- T-SWISS-T at 6
- serial range: 4.1m-Rxxx ?
- Pushers? MK1 (no line, until serial 6.0m/6.5m 1980/81) or MK2 (line)


Could you please share your views on the above? I assume there is obviously no precise database but glad if I can get feedbacks

Many thanks

Millerighe (mk0/1) up to 3.0. Mk2 pushers up to around 6m. Mk3/service pushers after that.

Overall the dial configs are correct. Personally I think it sometimes differes between silver and black dials. Especially early ones as I see black sigmas earlier than silver ones. Silver sigmas feels a bit more rare as well imho.

There’s more configurations than mentioned but in general they are correct. I think the change to sigmas is later than 2.8. Rather early 3m or at least 3.0. Bezels is a bit of a mess too but in general you have the mk1 until 4m and then use the others in quick succession.

Thanks a lot for the prompt feedback -

When you say there are more dial configuration, are you referring to big eyes dial? What is the serial number corresponding to this configuration?

With regards to service pushers, they are exactly the same as the what you refer as MK3 (post 6.0m with a line?)

Many thanks for the help!

Well.. You have the big eyes but also different standard dials with the print high/low, silver/white print, flat subdials etc. And of course the PNs..

Mk3 pushers used after 6m is p302 and are same as service. P300 is millerighe (mk0/1) and p301 is the standard ones used in the 70’s and known as mk2.

Got it with pushers, thanks Per -

Three other questions that I am trying to sort out:

1. Are the hands constently the same over the 6263 period ? How different are replacement hands?

2. With regards to flat subdials, I understand it is rare and not particularly linked to certain serial number, is this your understanding too?

3. Big eyes - I understand they appeared on both MK1 and sigma dials. Is there a certain serial range we have managed to find?

Many thanks for taking the time.

Same hands afaik.

I would expect them to be in the same era. Probably together with normal dials. Early 3m? Never had one.

Same here. Probably just a different batch dials and used together with non-big eye.

Thanks Per for sharing
I will continue my research and come back there if I have questions!
