you might need to provide some references to this because i dont think the Watchtower ever promoted the worship of Jesus.... even going back to before we were named Jehovahs Witnesses, the bible students were promoting Jehovah as the only true God and as the Father of Jesus. So i dont think they would have been promoting the worship of him.
Back in the Watchtower of 1881 they declared that Jehovah was the Supreme being and the God of the bible. Unless you can provide some reference, i cant really say if what you are saying is correct or not.
"It seems clear that His Divinity was retained in humanity because He repeatedly spoke of Himself as having come down from heaven, and because He, though passing through trial and sorrow as a man, was yet possessed of the authority and exercised the prerogatives of a God. He was the object of unreproved worship even when a babe, by the wise men who came to see the new-born King. Matt. 2:2-11. Even the angels delighted to do Him honor. "When He bringeth the first-begotten into the world, He saith, "And let all the angels of God worship Him." Heb. 1:6. He never reproved any one for acts of worship offered to Himself, but when Cornelius offered such service to Peter--the leading apostle-- "he took him up, saying, stand up; I myself also am a man." .... Had Christ not been more than a man the same reason would have prevented from receiving worship...." Zion's Watch Tower 1880 Oct pp.2-3
"It is undoubtedly proper enough for us to address petitions to our Redeemer and Advocate, who loved us and gave himself for us....Although we are nowhere instructed to make petitions to him, it evidently could not be improper so to do; for such a course is nowhere prohibited, and the disciples worshiped him." Zion's Watch Tower 1892 May 15 p.157
"Jehovah God commands all to worship Christ Jesus because Christ Jesus is the express image of his Father, Jehovah, and because he is the Executive Officer of Jehovah always carrying out Jehovah's purpose (Heb.:3-6)." Watchtower 1939 Nov. 15 p.339
