If it's quartz, then perhaps it's ETA G10 or a similar movement. The Valjoux I mentioned was for auto-chrono. RM8k for a Edox quartz chrono seemed to be rather steep of a price, no? Anyway, the good thing about the quartz are the affordable servicing. I recently serviced an Omega Speedy at the SC and it's controlled price for such a servicing was circa RM2.5k IIRC, but they did gave another 2-years warranty thereafter. When I sent a Tag quartz for servicing at the SC, it was only RM500 IIRC.
