Atmos transparent “Birth Date” (Ref. Q5145205)

In 2009, the Atmos transparent “Birth Date” was launched (Ref. Q5145205). The transparent case gives the Atmos an avant-garde look; the clock seems to float in a glass cube.
The special thing about this reference: there is a version with a light blue dial and a version with a light pink dial, each with the ATMOS lettering above.
Originally, this variant was intended as a birth gift, hence the small unengraved plaque on the front of the base.
