Reference 5070 was launched in 1998 and is one of the largest series produced wristwatches made by the company. The size and shape of the watch was based on a vintage oversized aviator-style split-seconds chronograph, ref. 2512; indeed, the dial of the 5070 is almost an exact replica of the ref.2512's. For images of the ref.2512, see Huber, M., & Banbery, A., Patek Philippe Wristwatches, Second Edition, p.274. Production of ref.5070 in yellow and white gold recently halted and it is believed that production of the pink gold model will cease shortly.
