As said, nothing mysterious... it's a stock number from the retailler Salvador Cupello in Venezuela.
There are several watches with these.

some more insight on issue mentioned.
Crown design: the crown can come off, as the monocock case has to use two-piece stem design and the coupling may get loose after years of duty...
Crystal: the service crystal is 1mm thicker, that the original. Thats also, why it is heavier. This means, that you have to use the service bronze step ring, as the genuine one is higher and when used with service sapphire, it will be to high to lock it with the ring.

Salvador Cubello still exists:
salvadorcubello.com
from there:

En 1950 la casa Omega de Suiza y su filial Tissot, le dieron a esa joyería la representación oficial de sus productos para toda Venezuela, y para atender esta nueva actividad se funda en Caracas la empresa “Salvador Cupello C.A.”, que inicialmente se radicó en la esquina de Bucare a Maderero, No. 198, oficina 8, y que luego, en 1952, se mudo al edificio José Mendozza, en la esquina de Gradillas a Sociedad, al lado de la Plaza Bolívar, adonde funcionó durante 50 años.

Y en el año 2001 Salvador Cupello C.A. se muda a su sede actual, en el Centro Empresarial La Pirámide en Prados del Este, PH-502. Durante más de 120 años Salvador Cupello C.A. ha trabajado en el ramo de la distribución y servicio técnico de importantes marcas de relojería, como Audemars Piguet, Jaeger Lecoultre, Omega, Tissot, Raymond Weil, Nivada y Spazio 24.
