Reloj was written by Mexican composer Roberto Cantoral in 1956 and became a bolero standard long before Luis Miguel recorded it for his 1997 album Romances. His polished version introduced the song to a new generation and remains the most recognised recording online. Clips of the chorus now circulate on TikTok and YouTube edits, where creators use its clock metaphor and pleading tone for breakups, unrequited love and overly dramatic romantic scenes.
