it uses the rare caliber 551
it is very old caliber with loads of good feature, the chronometer.
approximately produced at 1959
very rare and collectible
this variant is without the date, so no need to chage date. as it is almost grab and go.
I do like no date variant because the dial is balanced, ans symmetric.
case stainless steel there are sign of usage almost 70 years
dial and hands are original in great condition, there are some aging at the dial but itmakes the dial more authentic and has vintage vibe in it.
nevertheless, all marking on dial is intact. crosshair dial makes it uncommon variant.
original plexiglass with omega logo
original backcase with gold medal attached, sign of luxury or high end item
authentic leather strap
movement caliber 551 in good condition keep good time and long power reserve.
