Just got this one today, dont normally collect any thing Quartz but I make an exception for these as they are unique in their styling and getting pretty darn hard to find and prices are rising.
I now have a matching set with this new one and a previously collected black face and orange needles. Very pleased been smiling all day.
Hi @Spruce , it's a ref 2846. Interestingly the inside case back is stamped 2846 - 2848. I believe the 2846 was the correct reference when housing the central seconds cal 500 or 501 movements and 2848 for the small seconds cal 490 or 491.
