As above there’s a 600 spring drive diver on C24 for £1800, seems cheap.
Various MM300 at around 2k or even £2800 new
And the GS spring drive 2nd hand around 4k
Is there a huge variance in quality, and is that Spring 600 too cheap it seems a great price?
I am no seiko expert but the case sizes and quality and indeed the fact it’s not a ‘usual brand’ interests me greatly
Any advice gratefully recieved….. is the 2k extra worth if for the GS they really aren’t about in the used marketplace….
