Bosch 30" Benchmark Series speed combination double wall oven. The Bosch speed microwave combination oven features a wall oven with a SmoothClose door. Color TFT Touch control with SteelTouch™ buttons for easier operation of the oven. With Genuine European convection, we use a third heating element around the convection fan to circulate warm air more evenly throughout the oven cavity. The result? Even baking results on every rack.
