Do you have all of the Hanhart or LACO watch models in stock?
At any given time various models are in stock, but the Hanhart Luftwaffe Fliegerchronograph is a top seller, so this is almost always in stock or on perpetual order. Watches not in stock can usually be obtained from the respective manufacturers in about 4-8 weeks. However, if the purchase is intended as a gift, it is always best to allow plenty of lead time just in case your selection is sold out of current stock and on order. Gift certificates make very attractive alternatives if your selection is on order.
