Hands-On Debut: Parmigiani Tondagraph GT Annual Calendar Chronograph
Alongside the Tonda GT this week, Parmigiani released the Tondagraph GT, a piece that I think is their most compelling product in recent memory. Sharing the same basic case and design of the Tonda GT (which I went into in detail here), the Tondagraph GT is a steel leisure watch featuring an annual calendar chronograph with 100M water resistance.Somewhat ironically, the annual calendar chronograph is rarer than the more complicated perpetual calendar. In fact, other than Patek Philippe, Ulysse Nardin, and Richard Mille, it's hard to think of anyone else producing these.

I think this dash of orange adds just the right amount of color to a dial that is otherwise fairly monochromatic.

When trying to solve a problem, the beginning is always a good place to start. That’s exactly the process followed by Arnold & Son in their attempt to eliminate isochronal error from one of their newest pieces, the Arnold & Son Constant Force Tourbillon. Arnold & Son’s heritage exists in the legacy of John Arnold and his son, two of the greatest watchmakers to ever come out of England. So revered was Arnold that Abraham-Louis Breguet himself sent him his own son as an apprentice, while Arnold returned the favour. Having packed off his son to learn at the knee of the Swiss maestro, Arnold turned his attentions to the problem of the times: the quest for chronometric accuracy at sea.One of the greatest problems when it comes to accuracy is moderating the supply of power to the regulating organ of the timepiece (in this case, the tourbillon featured in the lower right quadrant of the dial). The mainspring, like any component of this size, is susceptible to certain m
