Introduced in 2002, the Valjoux (now ETA) 7753 is a cam-operated automatic chronograph with a date complication. It differs from the base ETA 7750 in the location of the chronograph minutes counter: Rather than 12:00, the subdial is at 3:00 as on many other chronograph movements. This gives watches using the ETA 7753 a different look from conventional 7750-based watches.
Cal. 7753 was a late addition to the lineup, being added in 2002 as many other members of the family were retired. The altered placement of the minutes counter increases the jewel count to 27 though thickness remains 7.9 mm. It also required the addition of a date corrector pusher at 10:00.
The ETA 7750 is available in Elabore, Top, and Chronometer grades, each with different specifications and materials used. The display layout is as follows:
- Central hour, minute, and chronograph seconds
- 30 minute chronograph hand at 3:00
- Date window at 4:30
- 12 hour chronograph hand at 6:00
- Running seconds at 9:00
Cal. 7750 is used by other manufacturers, often with additional finishing or complications. Specific movements that are substantially similar include the Breitling B23, Bremont BE-53AE, Montblanc MB 25.02 (formerly 4810/502), Hamilton H-31 (with 60 hour power reserve), Longines L683.2, Omega 3304, and Panerai OP XII. The ETA A05.H31 lacks the 12 hour counter at 6:00 while the Panerai OP XVIII has a rattrapante function. The La Joux-Perret LJP8120 similar.
