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; the visual novel volumes it adapts began publishing in 2017. (Frontwing, IMDb)

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: Murasaki's watch is drawn as the grey GD-350-8, the vibration-alert G-Shock whose silent flat-motor alarm suits an operator who cannot afford an audible beep. In Frontwing's visual novels she wears the black-and-red GD-350-1B; the anime redraws the same model in its grey colorway. The identification comes from a detailed fan analysis of the series' watch designs. (r/grisaia)

Casio G-Shock GW-M5610U-1ER: Chris, Class A's driver and gunsmith, wears the solar, radio-synced square G-Shock GW-M5610U-1ER in both the visual novels and the anime, per a detailed fan analysis of the series' watch designs. The multi-band square is the pragmatic pick of the group's most equipment-minded member. The accompanying wrist insert comes from episode 1 of the 2025 television continuation. (r/grisaia)

Casio G-Shock GW-M5610U-1ER: In the anime Tohka wears the same GW-M5610U-1ER square as Chris. In the visual novels she instead wears an unidentified Swiss-style dive watch with a countdown bezel, which the identifying analysis leaves open for lack of distinguishing marks; the analysis's hedge is preserved here.

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, the identification stays at family level. (r/grisaia)

Rolex Submariner 116610LN: Maki's dive watch is drawn as the ceramic-bezel Submariner Date 116610LN, a gift from her benefactor Nikolaevich within the story. 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)

Patek Philippe (unidentified model): Heiress Taiga arrives wearing a gold Patek Philippe the anime draws as a composite: a rose-gold Nautilus 5990/1R case reading with a 1990s Golden Ellipse dial, per the identifying fan analysis, so no single production reference matches the drawing. 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.
