Compatibilidad entre calibres

[Scuba dude]

Hola compañeros,

Estoy a la espera de recibir un reloj con calibre ETA/AS 536.121. No se si funcionará o no, así que mientras llega me gustaría ir buscando posibles recambios/sustitutos por si el calibre está totalmente inservible.

Este es el calibre que trae:

Y estas las características del mismo:

He buscado un movimiento igual en ebay y el único que hay ahora mismo está por 200€, mas del doble de lo que me ha costado el reloj que quiero reparar. Leyendo un poco por la red, he visto que hay un calibre que puede ser compatible, y que es más fácil (barato) de encontrar. Se trata del ETA 450.111:

Adicionalmente he leído que se ha conseguido sustituir el ETA/AS 536.121 por un ETA 2836 automático, cuyas características son:

Como véis he hecho mis deberes hasta dónde he podido. Atendiendo a las medidas vistas anteriormente, ¿alguien puede decirme si sería posible una sustitución directa? ¿Algún compañero relojero se atreve a meterle mano? ¿Alguna otra solución en caso de que sea imposible repararlo?



El reloj en cuestión lo he presentado en la sección vintage y se trata de este Rodania Pro Diver de 1970:

Gracias de antemano.
