I post this for information, seems like countless times I've been after a watch that is/has been discontinued, greatly frustrating my search for something that ticks all the boxes. So, I'll pass this along for people who might be sitting on the fence over this, my advice is , "get it while the getting's good".
It's sort of strange, this marketing decision, as it seems like the 656 is one of the best sellers for Sinn, both as an entry level, and as a simple pilot watch. But, I guess nothing lasts forever. The word on the street (straight from Sinn Germany) is the venerable 656 is going to be discontinued soon. It will possibly replaced by something similar, with full tegimenting. This is what I got from Maria in an email exchange:
"it is regrettably not planned to build a tegiment 656.
However, there will be a similar model with a tegiment case soon, approx. mid-July.
I will inform you as soon as I get more information."
"yes, 656 will be sold out soon.
This change might bode for other models as well, also. Anyway, this will hopefully clarify it for people looking, and they can get on the train before it leaves the station. The 656 is a great watch, from the accounts I've read. I'm tempted, but I just don't have the money right now, so I'll have to contend myself elsewhere.
Don't wait too long guys!
