As MMMD says, it's due to the halogen lighting in the room. It was a daily wearer for a number of years.
I can't get a good shot of this watch no matter how hard I try! Picture taken about an hour ago as I nurse a hangover:
Nice! My 265 says "hi" (see the family resemblance?)... But I'm actually wearing this ref. 6085 semi-bubbleback today: (I wish the weather were so nice today!)
Just came home from a long walk wit my dog. "Yuma" is tired and I make a pic of one watch I wear today...
Nice Tissot and great wrist 'presence'. [I tried taking a pic today with a watch on my wrist. Didn't work out at all.]
A slightly rough but perfectly working EternaMatic 2002 Chronometer out of the box today. Caliber 12824 (2824 with Eterna modifications - Kif-Ultraflex++). Not too many 2824 derived watches with Chronometer certified movements out there. Got a confirmation of the COSC certificate from Eterna based on the movement serial. (They could however not provide a copy of the certificate.)
