Case Details and Military Markings

The wristwatch is housed in a 36mm brushed stainless steel round case with fixed bars, shown fitted with an associated grey fabric strap and an associated steel buckle. The source documents that the screw-down case back is engraved with military markings reading '↑ 6645 101000 6B/542 4330/53'. These engravings are not visible in the provided frontal image and rely on the cataloguer's transcription.

Dial Configuration and Tritium Replacement

Visual inspection and auction documentation indicate a matte black dial featuring white Arabic numeral hour markers and an outer minute track accented with luminous five-minute dots. The dial displays polished sword hands with luminous inserts, a centre seconds hand, a military broad arrow, and a circled 'T' symbol positioned beneath the Omega signature. The cataloguer notes that this model was originally fitted with a radium dial, whereas the present watch is fitted with a later tritium 'Fat Arrow' replacement dial. According to the source, the circled 'T' signifies the transition from radioactive radium to tritium to adhere to post-war regulations.
