Whats the difference between a modular chrono and lets say a 7750?
i try to explain... i no expert....
-7750 is a chrno from the ground up. Means the whole chrno thinggy are intergrated into the movement. Downside is it is very tall and fat.
-2894 is basically a 2824 attached with a seperate chrono module.
When your service it:
-apparently the amplitude on 2894 will go crazy even after u full service it. Its found out latter that its the module that cause the friction hence causing the crazy amplitude. That why they replace the whole module itself whenever it go for service.
-Servicing 7750 should be no prob cause the whole thing is integrated into each other. (dunno how to explain on this)
Another example using car modding is:
-getting Wira and dump in evo engine and all upgrade its mod (ECU, Air intake, turbo, suspension and etc) to get in same power range and drivavity of F430 (2894)
-getting a Ferrari f430 without any mod but come together with a complete package from the factory (7750)
Hope you understand....
