Sharing what I believe to be a limited edition, late 90's S/EL, model WG1117-K0. I've seen several that are numbered (xxxx of 1500), as this one is. I also believe I've seen some with the same model number but an actual serial number, like other S/EL's. None of the numbered units have a second serial number. So, not sure if it started as a limited edition but then was converted into a production model or something else. Perhaps someone more knowledgeable can shed some light here. I've seen several available in Japan and this one is from Japan, maybe a Japan-only release?
Indoors the dial looks almost matte black, outdoors the dial pops!
Uniques for the WG117 as compared to the WG111A, which is the other blue dial quartz S/EL:
-> navy blue dial (vs. medium blue)
-> cream colored hour markers, date outline, and text (vs. white)
-> black chrome indices (vs. chrome)
-> monochrome white Tag Heuer insignia (vs. multicolor green/red/white)
-> no chrome inner ring (vs. chrome inner ring)
-> serially numbered "No XXXX/1500" (vs. traditional serial number)
