Greetings, and welcome to the world of IWC. Today I'll be your guide to the proper usage, care, and maintenance of your IWC Aquatimer 2000, Edition 35 Years Ocean 2000 in Titanium. This is reference 3291-01. This timepiece is automatic winding, yet it can be manually wound should it stop by taking the crown and turning it counterclockwise until it can be felt and heard popping out of its threaded sleeve. In this first position, turn 20 to 30 turns in a clockwise direction. This will be sufficient to start the movement. Now you can set the watch, set the date, and the timepiece will continue to wind itself automatically. However, should you wish to wind the watch to a full power reserve of approximately 42 hours, simply continue turning in a clockwise direction. You cannot accidentally overwind this automatic timepiece as the bridle style mainspring slips by design and relieves any strain. Listen for the subtle tick or click that it makes, that's your sign the watch is fully wound.

At this point you can use subsidiary functions to properly set the time and the date. Pull the crown out, two stops, two detents, until it halts. This is the stop seconds or time setting position. This can be us to synchronize to a known accurate reference time, such as an online atomic clock. The U.S. Naval Observatory is the best reference for one of those. On the Observatory's site, set the watch to the correct hour matching your reference and the next nearest minute. Wait for the reference time to match the hour, minute, and second you've set. That is wait for it to catch up precisely, push the crown back in, now you've synchronized to a reference time.

One detent out from flush winding position is the quick set date. This can be used to rapidly cycle the date should it run down or encounter an irregular length month. It's important that this function never be used between the hours of 8:00 pm and 3:00 am. This is the danger zone during which the watch is engaged in automatic turnover of its calendar. Never use the quick set during this period. Once you're done setting the time, always thread the crown back into a stop and its flush position for watertight integrity and protection from abrasion. 

The safe dive bezel, which is controlled by a differential housed under the grading at nine o'clock allows you to turn it with gloved or wet hands and move the index on the bezel unidirectionally. It can never turn in a clockwise direction, thus it can never accidentally extend a dive, only shorten it by accident. However, this system is very secure such that neither is likely. Align the index with the minute hand and now you have the ability to time an interval from 0 to 60 minute around the race of the rehaut the inner bezel. The inner bezel can also be aligned with the hour hand if you wish to time a longer interval.

The watch features a quick release strap system that is controlled by pull tabs. You grab the inner tab with a fingernail, pull it, and pivot the strap away from the case. No need to intervene with a jeweler's help nor special tools, your fingernail is sufficient. This allows closer cleaning of the case, or swapping of straps and bands. You replace the strap the same way you removed it by first placing the channel on top of the bar and pivoting it forward until you hear a click. Now it's secure. 

There are three areas of hazard with respect to the handling of this timepiece that you should keep in mind, water, magnetism, and shock. Now the timepiece is rated as water resistant to 2,000 meters, which IWC deems sufficient for any professional diving activity. However, it's important to remember that should you wish to use the watch for diving, or even if you simply wish to use your watch in water, water test no more than 12 months apart. The 12 month interval is recommended by IWC to ensure that factory rated hermeticity is retained. 

Moreover, only these agencies are authorized to back all labor and parts invested with an IWC factory service warranty. A comprehensive service will include everything from replacement of a worn strap to restoration of a worn case to factory specifications, polished and beveled with the graining in the correct direction. It will result in restoration of water tight integrity to factory specifications as well as cleaning, oiling, and adjustment of the caliber. It's important to text, call, or email our experts at govbergwatches.com with any questions you may have regarding the usage and the care of this or any IWC fine timepiece.
