Grisaia: Phantom Trigger (2019)

Bibury Animation Studios' adaptation of Frontwing's Grisaia: Phantom Trigger visual novels, following the armed "sapper school" students of a rebuilt Mihama Academy: handler Haruto Aoi's Class A of trained young operators. The animated series began with two 2019 theatrical episodes and returned six years later as a thirteen-episode television continuation broadcast between January and March 2025; the visual novel volumes it adapts began publishing in 2017.

The franchise's costume design gives each operator a specific, consistently drawn wristwatch, and the identifications below rest on one unusually detailed fan analysis of those designs across the visual novels and the anime; the analysis names its cues, and its own uncertainty about individual models is preserved in each record.

Watches

Casio G-Shock GD-350-8: A fan analysis identifies Murasaki's anime watch as the grey GD-350-8, a vibration-alert G-Shock, and distinguishes it from her black-and-red GD-350-1B in Frontwing's visual novels. (r/grisaia) The reviewed opening montage of the 2025 television continuation instead shows the same "CAZIO" MULTI BAND 6 square Tohka wears. No reviewed frame confirms a GD-350, so that model remains the fan analysis's unverified identification.

Casio G-Shock GW-M5610U-1ER: Chris, Class A's driver and gunsmith, wears the solar, radio-synced square G-Shock GW-M5610U-1ER, which a detailed fan analysis of the series' watch designs places in both the visual novels and the anime; the multi-band square is the pragmatic pick of the group's most equipment-minded member. The wrist insert here is from episode 1 of the 2025 television continuation, and that is the generation this reference can belong to: Casio introduced the GW-M5610U-1ER in 2021, two years after the 2019 theatrical episodes, and the analysis was written during the 2025 broadcast without separating the two. A square drawn in the 2019 episodes would instead be the visually near-identical GW-M5610 that the 2021 "U" revision replaced. (r/grisaia)

Casio G-Shock GW-M5610U-1ER: In the anime Tohka wears the same GW-M5610U-1ER square as Chris, on the same evidence and with the same limit: the reference dates to 2021 and so postdates the 2019 theatrical episodes, while the analysis identifying it was written during the 2025 television broadcast and never says which generation of the animation it describes. In the visual novels she instead wears an unidentified Swiss-style dive watch with a countdown bezel, which the analysis leaves open for lack of distinguishing marks. (r/grisaia)

Casio G-Shock: Rena's watch is an analog-digital G-Shock drawn with a GMT-style bezel, described by the identifying analysis as a Gravitymaster-type variant it could not match to a production reference, and recalled by a second fan as a blue-bezel Gulfmaster. With the two accounts naming materially different lines, only the G-Shock family is confirmed, not a specific model. (r/grisaia)

Rolex Submariner 116610LN: Real-adjacent identification: a fan analysis reads Maki's dive watch, a gift from her benefactor Nikolaevich, as the ceramic-bezel Submariner Date 116610LN. In one visual-novel ending Taiga replaces it with a "Pepsi"-bezel GMT-Master II 126710BLRO, a narrative beat the anime does not depict. Both identifications come from a detailed fan analysis of the series' watch designs. (r/grisaia) Episode 12 of the 2025 television continuation gives the watch a full insert, held in both hands in the sickroom sequence of the Nikolaevich flashback rather than worn: a steel diver on an Oyster-style bracelet with a black bezel, oversized round luminous markers, Mercedes hands and a cyclops date at 3 o'clock, the dial lettered SUBMARINER under a crown and the parody name RALEX, so the drawing confirms the Submariner Date design the analysis names.

Patek Philippe (unidentified model): The fan analysis compares heiress Taiga's gold watch with a rose-gold Nautilus 5990/1R case and a 1990s Golden Ellipse dial; it identifies no single matching production reference. In the visual novels her watch, a gift from her cousin Ichiru, reads instead as a vintage Grand Complication on a brown ostrich strap, and the story later has Haruto issue her a plain square G-Shock in its place. (r/grisaia) The episode 8 frame shows the watch in yellow gold, case and bracelet set with baguette stones, a dark dial with two registers and LOCAL and HOME legends; the rose-gold reading is the analysis's, not the frame's.

Casio G-Shock GW-M5610U-1ER: Taiga's second watch: the fan analysis of the series' watch designs records that in the anime handler Haruto issues Taiga a GW-M5610U-1ER, the same solar, radio-synced square G-Shock Chris and Tohka wear, in place of the gold Patek Philippe she arrives with, where the visual novels give her what the analysis reads as a DW-D5600 instead. The analysis names no episode; Taiga's arrival in Class A opens the "Mother's Cradle" arc that begins the 2025 television continuation, and the reference dates to 2021, so the row belongs to that continuation rather than the 2019 theatrical episodes.

Panerai Luminor Marina: Class A's handler Haruto Aoi wears a steel Panerai Luminor Marina on a black leather strap: episode 2 of the 2025 television continuation gives his wrist a full insert in which the crown-protecting bridge, the Arabic 12, the small seconds at 9 and the dial lettering LUMINOR MARINA and PANERAI are all drawn legibly, and the same watch sits on his clasped hands in the episode's opening. The lettering settles the brand and line; no reference number can be read from the drawing, so the family-level page is used.
