New Casio sapphire crystal-equipped watches revealed ahead of launch in four variants

Casio looks to be adding a rectangular watch to its Beside line. Images of four unannounced references surfaced on Thursday via @geesgshock, an Instagram account that regularly (and reliably) posts Casio material ahead of announcement.
The leak names BMS-105D-1A, BMS-105D-7A, BMS-105L-1A and BMS-105L-7A, and puts the launch in September. Casio has not announced anything. Even the account describes its own images as fuzzy and poorly cropped.
If we read these against Casio's naming conventions, the D references come on steel bracelets and the L references on leather, with 1A denoting a black dial and 7A a white one. That yields two dial colors across two strap options, which matches what the images show.
The case is rectangular in polished steel — the watches have a stepped bezel and an integrated lug design. Dials feature Roman numerals at 12 and 6 with baton markers elsewhere, an inner rectangular frame, and the vertical line motif which Casio normally uses in its Beside range. Three hands, but no date window is visible. The leaker also reports a sapphire crystal. This is reinforced by the fact that the dials in the images look to carry a sapphire marking beneath the Beside wordmark.
Nothing else is confirmed. No case dimensions, price, movement, water resistance or launch markets have been mentioned; @geesgshock states it does not have measurements.
The existing BMS-100 measures 47.5 by 40 by 9.1 mm, while the smaller BLS-100 is 34.5 by 28.2 by 8.2 mm at 50 m with an SR626SW cell. Both use sapphire. Casio also sells the rectangular LTP-B150 (see featured image) at $89.95, but that watch uses mineral glass, so a sapphire alternative would definitely be priced above it.
Rectangular dress watches have been quite busy this year. Citizen launched a rectangular Dress Classic line in the UK, and Timex has also revived two rectangular platforms since March.
