The Breitling Navitimer, a legendary pilot's watch renowned for its iconic slide rule bezel and sophisticated mechanics, can sometimes present a unique challenge to its owners: setting the date. Unlike many modern watches with independent date-setting mechanisms, the Navitimer's date wheel is linked to the hour hand movement, requiring a specific procedure. This article will provide a detailed, step-by-step guide on how to correctly set the date on your Breitling Navitimer, covering various models and addressing common concerns. This information supplements, but does not replace, the official instructions provided in your Breitling Navitimer user manual, Breitling Navitimer owners manual, or any specific model manual such as the Breitling Navitimer A24322 manual or Breitling Navitimer B01 manual. Consult your official documentation for specific details pertaining to your watch model. This guide aims to clarify the process and address some of the common frustrations experienced by Navitimer owners.
Understanding the Mechanism: Why it's Different
Before diving into the steps, it's crucial to understand why setting the date on a Navitimer differs from simpler watches. The date mechanism in the Navitimer is integrated with the hour hand movement. This means that the date changes only when the hour hand passes through midnight. This design choice, while adding to the watch's mechanical complexity and charm, necessitates a slightly more involved procedure than simply pushing a button or pulling a crown. This is different from the simpler date-setting mechanisms found in many other watches, including some other Breitling models. The Breitling Emergency, for instance, has a different mechanism altogether and should not be confused with the Navitimer's date-setting procedure.
The Standard Procedure: Step-by-Step Guide
The following steps outline the standard procedure for setting the date on a Breitling Navitimer. Remember to always consult your watch's specific manual (Breitling Navitimer instructions, Breitling Navitimer user manual, etc.) for any model-specific variations or cautions. Incorrectly manipulating the crown can damage the delicate internal mechanisms of your watch.
Step 1: Pulling the Crown: Carefully pull the crown to its second position (usually, this is the position that allows you to set the time). This position will disengage the time-setting mechanism and allow you to adjust the hands independently.
Step 2: Advancing the Hands Past Midnight: Slowly turn the crown to advance the hands. Your goal is to advance the hands past midnight. This is crucial. The date will only change *after* the hour hand passes the 12 o'clock position. Do not rush this step; smooth, controlled movements are essential. Pay close attention to the date window; you should see the date change as the hour hand passes midnight.
Step 3: Backtracking to Approximately 8:30: After the date has correctly changed, carefully rotate the crown backward, moving the hands counter-clockwise until they reach approximately 8:30. This seemingly counterintuitive step helps to ensure that the date mechanism correctly registers the change. This is a critical step and omitting it can lead to date-setting issues.
