Watches: Graham London Silverstone RS Endurance 12H & 24H (+live pics)

By Thierry Ané on June 6, 2014

Since its early days, Swiss watch brand Graham has built its reputation on rugged sports watches with strong and immediately identifiable designs. Inspired by the world of racing, the “Silverstone” collection definitely pushed the boundaries of the motorsports aesthetics with the use of strong contrasting colours, large Arabic numerals, protruding chronograph pushers and crown, and the iconic tyre-tread rubber strap.

Such uncompromising design codes are not to everyone’s taste, though, and it seems that with the introduction of the Silverstone RS Skeleton line last year, the brand has decided to take a more refined and somehow more technical approach to the racing look.

With a more conventional-looking case but through the use of technical materials, complex constructions, subtle blue, green, or red accents and a skeletonised dial, the brand came up with a truly luxurious-looking chronograph model able to sustain the comparison with equivalent models from traditional actors of the high-end sports watch segment.

The introduction of the RS Endurance 12H and the RS Endurance 24H during the Basel fair confirms that the brand has now opted for a resolutely more refined approach to motorsports that should quickly catch the attention of many watch aficionados.

At first glance, one could think that the RS Endurance 12H and the RS Endurance 24H are simply the orange and red renditions of the same watch. Unlike last year’s models, though, these two watches differ by more significant aspects than the colour theme. The former houses the self-winding G1735 chronograph calibre while the latter is powered by the G1751 movement. This automatic calibre also features a chronograph but this time with a flyback function. The Silverstone RS Endurance 24H is also limited to 250 pieces whereas the RS Endurance 12H will be part of the permanent collection.

Aesthetically, though, both watches are quite similar. They share the same round 46 mm stainless steel case with a black DLC coating paired with a black ceramic bezel featuring an orange or red tachymeter scale. They are both mounted on the brand iconic tyre-tread rubber strap with an orange or red insert and a black DLC steel folding buckle. However, they are both available with a black alligator strap and black DLC pin buckle if you want to emphasise the sport-chic side of these beautiful watches.

Like last year’s RS Skeleton models, these two watches showcase a beautiful aluminium ring (orange or red) with “Clous de Paris” decorations underneath the ceramic bezel. It reinforces the overall racing look but also brings a refined touch to the watch. The new watches also present a skeletonised dial like last year but the aesthetic effect is totally different due to the black treatment of the mainplate and the presence of a smoked sapphire (the sapphire back is also tinted on both models).

The colour touches are also more important on these models, partly due to the presence of an entirely visible date disc with orange and white or red and white stripes referring to circuit vibrators. The motorsport allegory is also enhanced by the presence of an automobile pulley-shaped seconds counter at 9 o’clock on both models.

Lastly, and in case you were wondering what the significance of the “12H” and “24H” part of the name was, it refers to the difference in the hours counter of the chronograph: it measures up to 12 hours on the RS Endurance 12H and can indicate up to 24 hours on the RS Endurance 24H. This slightly unusual feature is also indicated on the red chronograph pusher of this model, positioned at 4 o’clock.

Both versions are equally stunning and I really like how the brand paid attention to the smallest details to create refined sports watches for demanding watch lovers. I am really impressed by the “Silverstone RS” line that has already become my favourite from this brand: there is not a single “Silverstone RS” model I would not be happy to wear.
