There's no mistaking how the 6138-3009 got its nickname, and at 42mm the "Jumbo" has certainly earned it. It's size, however, is in scale with its sophistication. The matte black multilevel dial is trimmed in lean contrasting markers, and is framed perfectly by the understated and steeply angled chapter. The white hour and minute baton style hands are a seamless addition, but its the sunny yellow chronograph hands that add a balanced color pop. The case is well detailed and to say it has wrist presences is an understatement. Contoured end links perfectly integrate the bracelet which provides a comfortable and finished appearance. Independent day and date quickset, and the option to manually wind the mainspring give the 6138 clear advantages over its predecessor. The chronograph functions are crisp and responsive, and post service, it’s keeping near perfect time. This example from May of ‘74 is completely original, crisp and unpolished, and a timeless classic bound to be a front runner in any vintage collection.
