Aibou: Tokyo Detective Duo

Aibou: Tokyo Detective Duo (相棒, Aibō, "Partners") is TV Asahi's flagship police procedural, following Inspector Ukyo Sugishita (Yutaka Mizutani) of the Tokyo Metropolitan Police Department's Special Missions Unit through a series of rotating partners since its June 3, 2000 premiere; the franchise has run to 24 seasons and more than 450 episodes, plus six theatrical spin-off films. (IMDb) Hiroki Narimiya played Sugishita's third partner, young detective Toru Kai (甲斐享), across seasons 11 through 13, from October 2012 to March 2015, between Mitsuhiro Oikawa's Takeru Kanbe and Takashi Sorimachi's Wataru Kaburagi.

Watches

Diesel DZ4224

Worn by Hiroki Narimiya as Toru Kai. Two independent Japanese sources identify Kai's watch throughout season 12 (aired October 2013 to March 2014) as a gunmetal Diesel DZ4224 Overflow chronograph: 10keiya, citing Oricon, and the long-running celebrity-watch site watch.daygate.com, which states the piece was worn "consistently" (一貫して) all season, unlike the three different Diesel models Kai cycled through in season 11. watch.daygate.com anchors the identification in a plot beat from the season's sixth episode, "Ukyo's Watch": after Kai teases Sugishita for running ten minutes late, it emerges that Sugishita's own beloved mechanical watch has drifted, and Kai taps his own wrist and needles him that a quartz movement like his never loses time. Neither source is a production or supplier participant. (10keiya, watch.daygate.com)

Diesel DZ4297

Worn by Hiroki Narimiya as Toru Kai. The same two independent sources identify Kai's watch in the first two episodes of season 13, which premiered in October 2014, as a rose-gold-tone Diesel DZ4297 "Overflow Chronograph." watch.daygate.com specifies that the large gold-toned piece appeared in "both episode 1 and episode 2" of the new season, a materially distinct watch and a non-overlapping season from the gunmetal DZ4224 above. Neither source is a production or supplier participant. (10keiya, watch.daygate.com)

Girard-Perregaux Vintage 1945

Worn by Yutaka Mizutani as Ukyo Sugishita. In season 14 (2015–16), Konta Watch Blog identifies Sugishita's watch as a steel Girard-Perregaux Vintage 1945, which it records as Ref. 25835-11-221-BA6A. Its frame shows the curved rectangular steel case with a light dial on a black strap at his wrist as he opens a red pouch on a table; the reference is not legible in the frame and rests on the blog alone. In OCEANS's watch column, published during season 19, the editor Natsuki Ando independently names the Girard-Perregaux Vintage 1945 as one of Sugishita's signature rectangular watches and points to its appearance in the first episode of season 13.

Cartier Tank Solo SM WSTA0030

Worn by Yutaka Mizutani as Ukyo Sugishita. In season 19 (2020–21), Konta Watch Blog identifies Sugishita's watch as a small steel Cartier Tank Solo, Ref. WSTA0030. Its frame shows the rectangular steel case on a black strap at Sugishita's left cuff as he sits with hands folded over a navy suit; the blog's reference is not legible in the frame and rests on the blog alone. OCEANS's watch column, published during season 19, independently notes that Sugishita wears Cartier in the current series, without naming a model. (Konta Watch Blog; OCEANS) The Nakano Broadway watch dealer Renzu, writing at the start of season 20, recalls the season 19 watch as the large Tank Solo rather than the small model the blog names; the two accounts disagree on the case size.

Cartier Santos-Dumont SM WSSA0023

Worn by Yutaka Mizutani as Ukyo Sugishita. For season 20 (2021–22), Konta Watch Blog identifies Sugishita's watch as a small steel Cartier Santos-Dumont, Ref. WSSA0023. In its frame the square steel case on a dark strap shows at the wrist of his grey suit while a white-gloved hand works beside it; the dial is not legible and the reference rests on the blog alone. (Konta Watch Blog) Renzu, a Nakano Broadway watch dealer writing the day after the season 20 premiere, instead identifies a larger Santos-Dumont, either the extra-large Ref. WSSA0032 or, which it judges more likely, the large model, Ref. WSSA0022; the two accounts disagree on the case size. (Renzu)
