Apple is expected to produce approximately five to six million units of its three Apple Watch models, the Wall Street Journal reports, mentioning that half of the first-quarter production orders are slated for the entry-level Sport model. 

Meanwhile the mid-level stainless steel version is expected to account for one-third of this production with the rest of the units being the high-level Edition model made of gold. 

Respectively, all three of these models could have prices as high as $400, $650 and $4,200, according to BGR, which accounts for extra bands and unexpected expenses. However, Apple officials have mentioned that the Sport version begins at $349. 

"The Apple Watch will be instrumental in taking the wearables market to the next level of growth," CCS Insight research official Ben Wood said in a statement Tuesday, according to CNET. 

"If successful, it'll create a rising tide that will lift the whole market."

Apple is said to have dropped several health-related features from its Apple Watch development due to sensor issues involving inconsistency and inaccuracy.
