How to say "accurately" in Japanese

• きちんとJLPT N3approx.Common
  adverb, suru verbThe everyday choice for 'accurately' meaning done neatly, exactly, and without sloppiness. As a common mimetic adverb, it fits careful, precise handling of everyday tasks — doing work, answering, or arranging things properly.
  私の時計とけいはきちんと動うごいている。↗

  My watch is running all right.
• そつなく
  expression, adverbA less common word, usually written in kana alone: it matches 'accurately' as 'flawlessly, without making any mistakes' — carrying a task through smoothly with no slips or blunders, rather than with measured precision.
  仕事しごとをそつなくこなすことを会社かいしゃは求もとめていることはわかります。↗

  I know companies are looking for work carried out flawlessly.
• きちんきちん
  adverb (with と)A reduplicated mimetic form glossed 'correctly; properly; accurately', but much less common than きちんと and seldom the word learners need; for this sense of 'accurately', きちんと is the one to reach for.
• 正しくただしく
  adverbIts core senses are 'right' and 'correctly' — acting or judging in accordance with what is correct — so 'accurately' fits only loosely. Choose it when the point is being correct rather than precise or flawless.

Use 「きちんと」 for doing something neatly and exactly, 「そつなく」 for carrying a task through without any mistakes, 「正しく」 when the point is simply being correct, and treat 「きちんきちん」 as a mimetic variant you will seldom need.
