5 Sports Speed-Timer, Taupe Dial
Chronograph Kakume 6138-0030 — 5 Sports Speed-Timer, Taupe Dial
The dial carries 5 Sports Speed-Timer printing, dark square registers and luminous arrow-shaped hour and minute hands. Its photographed back reads 6138-0030 with a visible 4N serial prefix, although the dealer table says 6NXXXX. The dealer describes the present taupe colour and yellowed minute track as aging, not a separate factory colourway.
The dealer title dates this specimen to 1974. Its reused stock number also appears on a different Speed-Timer listing with a photographed 6N prefix. No production bounds or unique identity are inferred from the stock number. Past light polishing and unknown service history are disclosed; originality and UV observations remain dealer assessments.
