One of the many things that make time-only Group B so great are its impeccable dimensions. The 39mm titanium and steel case measures 39mm in diameter, and a scant 9mm in thickness. When paired with the flat link (kinda sorta) integrated bracelet it presented beautifully on the wrist. The inclusion of a chronograph in these latest renditions changes that, as you might have suspected, but not by much. The Group B Chronograph measures 40mm in diameter, and has grown to 13.4mm in thickness, all incredibly impressive numbers for a watch using a Sellita chronograph and a price under $1,500. 

Perhaps the most unique element of the Group B Chronograph is the design of the dial. The sub-dials are set within a carved out section of the lower portion of the dial, taking on the look of an old-school dashboard layout. That section of the dial is presented in contrasting tones to the upper portion of the dial, and creates some of the more compelling design choices within the colorways. There’s more than a hint of the famous Seiko Giugiaro chronograph here, and that’s not a bad thing by any stretch. One thing to point out, the hand design has been changed from the existing Group B, and no longer features the large overhang of the counterweight, so you won’t be seeing multiple hour hands here.

Inside, Autodromo is using the Sellita SW 510 M B movement, a manually wound chronograph with 63 hours of reserve. We’ve seen this movement used with increasing frequency across the realm of micro-brands from brands like Farer and Nivada Grenchen, to Massena LAB and Hanhart. It’s proven to be a great base and certainly keeps the wearability in check, and Autodromo has managed to price it on the lower end of what we’ve seen, at $1,495. 

The Autodromo Group B Chronograph is available exclusively through the Hodinkee Shop, and each colorway is limited to just 100 units. Autodromo.
