RGM model 110-A automatic alarm watch

RGM, American brand based in Lancaster, Pennsylvania, first introduced its alarm watch in the late 1990s, but the Swiss movement that they used then went out of production. Recently they were able to obtain some of these calibres, the La Joux-Perret 5900 automatic, and so the Model 110-A Alarm watch has been brought back into production, albeit in a limited series. It’s a welcome addition to the very small category of alarm watches.

The watch has a stainless steel case, 38.2 mm in diameter and 12.8 mm thick, with a lovely guilloché dial that recalls the superb finish of Breguet watches – a feel reinforced by the blued steel hands in Breguet shape. There are two crowns, one for setting the time and date, and one for winding and setting the alarm. This crown also acts as an on-off switch for the alarm: the alarm is off when the crown is pushed down, and switched on by pulling it out. Both the movement mainspring and the alarm spring are wound by the oscillating weight, but after the alarm has sounded – it operates for about ten seconds – the alarm spring can be rewound by hand using the crown so that it can be used again immediately. It’s a lovely piece, available from RGM for $4,950.
