Original model released in 1983. Really hard to find brand new. The Seiko 7A28-5000 is an easily identifiable watch, thanks to its distinct steering wheel-shaped casing. It is this shape that earned it the nickname Steering Wheel in collectors circles. The casing and the links in its rubber bracelet were in black chrome (PVD).The black dial features SEIKO in white and CHRONOGRAPH in red at the 9 oclock mark. Hour and minute markers are big and small dots, respectively.
The hour, minute and sub dial hands are white, while the chronometer second hand is red. The watch features three sub dials at the 12, 3, and 6 oclock positions, but in other models this vertical arrangement becomes a more normal horizontal layout. Press the button at 11 oclock and the chronometer starts and stops.Reset is at 2 oclock. The centre second hand ticks off seconds, while in normal operation the second hand is the subregister at 3 oclock. The 5/100th second dial is at 12 oclock and this moves in 1/20th second intervals. The 3 oclock dial shows seconds during normal operation, and the 6 oclock dial counts minutes as the center second hand completes a rotation. The chronometer function is by the upper left corner button, and the split function is at 7 oclock.
This watch is part of Seiko Speedmaster collection designed by Giugiaro. The 7A28-5000 can be identified through two reference numbers: SBBJ001 and SBBJ0011.

The watch is quite bulky to wear sitting high off the wrist. The Speedmaster case back features 10 bar water resistant protection, and has the corresponding 2 wave insignia. The model number 7A28-5000 is engraved on the case back, and is more commonly referred to than the series number SBBJ001. The Case back reads: ST.
