A few days ago, Bo Laishi launched a new series - Bellytanker series , temporarily consisting of two watches, the two watches on the use of a retro round case. Bellytank originated in the forties and fifties of the last century. The term originally referred to a sub tank installed in the abdomen of a warplane for emergencies.

Say something else Earlier, many watch friends that B01 and 4130 movement comparable, this is actually a reason. Both have a "blood relationship": Breitling dug away the Rolex 4130 movement development team to develop the B01 movement based on the 4130. Breitling B01 and Rolex 4130 so the same configuration and technical indicators. So since both are "the same" movement, Tudor why not directly from the Rolex movement to use. There are two reasons for this. One is that the direct use of the Rolex movement by the Tudor will greatly increase the cost of the Tudor watch and raise the price. Breitling B01 movement conducive to controlling the final price (it turns out, Tudor price control is very good). Another important reason is that the Tudor Rolex movement will affect the brand value of Rolex. Tudor and Bo Laishi these two chronographs are priced at 30,000 yuan in the early . At the moment, it seems that the Tudor will be slightly better, but Bolashi also has its own design features. Count the true history of these two chronographs are less than one year old, is a baby, have to grow slowly to withstand the test of the market. So these two "Daytona alternative", who would you choose?
