To mark its 150th anniversary, TAG Heuer will re-issue the Silverstone Chronograph in February 2010 as a limited edition piece. Originally introduced in 1974, the Silverstone is instantly recognizable by its cushion cut-shaped case. Just like the Swiss brand has initially promised, the 2010 TAG Heuer Silverstone Chronograph is almost identical to the original model both inside and outside. Powered by an updated version of the Calibre 11 with Dubois-Depraz module, the new Silverstone chronograph will be available in blue or brown dial version, with each version limited to 1,500 pieces. And the new Silverstone chronograph will come with matching perforated alligator straps and stainless steel cases. The new Silverstone’s only problem is its price. Limiting its total production run to only 1500 pieces, TAG Heuer plans to charge as high as $6500 for this beauty.
