Salesperson Rina Movsisyan (R) shows a Shinola watch, assembled in Detroit, to customer Ron Cromartie at Shinola's recently opened luxury watch and bike store in midtown Detroit, Michigan July 22, 2013. For nearly six decades Detroit's story has been one of relentless erosion of its once mighty manufacturing base, but even as the Motor City faces a long bankruptcy a clutch of small producers has moved in to rekindle the "Made in Detroit" brand. The largest of the city's small newcomers is a watch maker called Shinola, a Depression-era brand name purchased in 2011 when the company set up shop. Dallas-based Bedrock Manufacturing, a venture capital firm backed by Tom Kartsotis, founder of accessory firm Fossil Inc., decided to take advantage of Detroit's underutilized workforce and resonant Made-in-America mystique.

The long-banned liberation movement took power in 1994 after Mandela negotiated an end to apartheid with the white-minority government. Capitalising on its role as the standard bearer in the fight against apartheid, the party has dominated politics since then, but bitter faction-fighting and accusations of rampant corruption have raised questions about how long it will continue to lead Africa's biggest economy.
