Este movimiento es mi favorito, no solo por ser el primero en mover la saga Amphibian, sino por su robustez y hasta precision. He conseguido poner 2 de los mios en +/-10seg/dia.
Hoy buscando otra cosa he encontrado esto: ETA 2360:
Como veis el parecido es importante con esto:

Tambien me ha llamado la atencion la variedad, tanto en marcas, desde 2209 a secas, a iluminado en rojo a 2209SU.
Los mas antiguos, creo, son los que llevan el volante con contrapesos y el tambor del muelle con las estrellitas. Los 2 que tengo asi estan montados en relojes civiles no divers.
Sabeis algo del tema?
Description
Before the Chistopol movement factory launched the still currently produced movement series of the caliber 2414 and relatives, they produced movement with a diameter of 22mm, such as the caliber 2214 shown here. The specimen shown here still got the old image mark.
This movement is special due to its unusual structure and of course of its gloden screw balance, which is even connected to a breguet-type hairspring with (short) regulator arm and runs in two inhouse shock protections.The construction with its decentral minute wheel is unusual, too, but it is already a very modern one. This decentral wheel allowes a signficantly larger balance wheel which increased the precision. Since the center second hand is driven indirectly, we have the unusual situation of having five gears instead of the usual three or four.
What you also can see is, that the edges of the bridges and cocks are angled, so that this movement looks very nice, even without decoration stripes.
