Undeterred by Tim Cook's browbeating, supply chain 'guesstimators' soldier on with Apple Watch appraisal

IHS Technology tore down the 38-millimeter Apple Watch Sport, estimating that its total component cost comes out to just $83.70, as noted by ZDNet. The aluminum model retails for $349.

The LG-manufactured OLED display assembly and Analog Devices touchscreen controller combined for the highest part cost at $20.50 per device. The internal application controller is thought to come in at $10.20, while $7.20 is allocated to memory and $5.50 to power management.

Wireless interfaces add a further $3 to total, with audio and NFC devices accounting for $5.50 and sensors at $3.

The Watch's battery is estimated at an almost laughably low $0.80, while "other mechanical / electro-mechanicals," like wristbands and switches, add $16.50. IHS estimates the cost of packing and the new inductive charger to be $9.

Not included in the bill of materials estimate was outlay for research and development, marketing, or other expenses.

On Monday, Apple's chief executive said he had never seen such an analysis that was "even close to accurate." His testy response was prompted by questions about perceived weakness in the Apple Watch's launch margins.
