Hello, any information please. Inside is kf360. Sorry for poor english. Watch is in servise at a moment. Winding stem is split. Winding crown is with external thread. Back cover is monolithic. Does serial numbers dates watch to 1946? Is it prototype? Bought from Italy. Thank you regardless.
This one's a little different, a Biostar Electronic that informs the owner of their daily biorhythm, it's (unsurprisingly) the only watch to use an ESA 9156 Dynotron movement (rebadged 28-353).
Just back from my watch doc it's now correctly set up so I know how I feel intellectually, emotionally and physically which would be very handy if I believed (I don't) and it doesn't show the date, that's a day window so it's day 6... Saturday! So all in all pretty useless and yes I love it!
I’ve just joined the Certina club with this recent purchase inbound to me. I’ve had the vintage Super PH1000 on my short list for a while, and recently this came up on eBay at a reasonable price. A rather heavy black rubber deployant strap will be fitted first, but I’m also considering a black IsoFrane.
I have an Omega Chrono GMT diver, which is a substantial lump to wear- however this Certina may feel and look like I’m wearing a small volcano… but I’m up to the challenge. (Smile)
