Orient is owned by Seiko and the 469 movement thats put in to the makos is a solid workhorse with 40 years on it, you can get them for 100-150 bucks and its watch that provides great value.
But if you want something discrete, nice and provides great value,

The new Seiko 4R3X movements which is the economy version of the 6R15. the mainsping and adjustment is from the older 7S series movement making it a bit harder to adjust and reducing the power reserve from 55h to 45h.
It has both hacking and handwinding which the mako hacks. hacking means you can stop the seconds hand while adjusting the time to put it accurate to the second, and handwind means you can charge it by turning the crown aswell as moving the automatic rotor weight. both abilities the mako lacks.
If you want to spend the extra cash and want a simpler looking watch but that has more class (in my opinion).
That seiko 5 can be worn with a suit. the mako cant.
