Winding Index: IWC Winding Settings

This page is IWC's entry in the Winding Index — our census of how automatic watches wind, built from 4,302 audited model records. It is the data page: the settings IWC actually uses, counted across the range. For winder recommendations for this brand, see our Best Watch Winder for IWC buying guide; for an individual model's exact setting, the TPD settings index.

The story in the data

IWC is the deepest-covered brand in the entire Index — 274 published models — and it is firmly an 800 brand. The median IWC needs 800 TPD, and 59% of its models sit at exactly that figure. But IWC has a tail nobody else in the mainstream matches: 47 models (17%) need 1,000 TPD, the big-cased end of the range — the Big Ingenieur 5005 among them — where larger, heavier rotors and movements simply ask for more work per day.

Direction is where IWC owners need to pay attention. Three quarters of models (74%) are bidirectional, but 24% wind clockwise only. That is a high single-direction share for a brand this size, and it means an IWC on a counter-clockwise-only winder programme is a watch quietly running down. Set bidirectional, or check the model.

Extremes and spread

The least demanding IWCs — the Aquatimer line among them — sit at 650 TPD. The hungriest are the 1,000 TPD models at the top of the range, a figure shared by only 47 watches in the whole Index.

Setting	Models
800 TPD	163
650 TPD	62
1000 TPD	47
725 TPD	2

Against the average watch

Against the all-watch picture (median 650, 39.3% one-direction), IWC sits a clear step hungrier and a step more direction-sensitive than average. Across all 4,302 watches in the Index, the median is 650 TPD, 90.2% of watches need between 650 and 800 TPD, and 39.3% wind in one direction only. The full census is in the Winding Index report; how the data was audited is on the methodology page.

Frequently asked questions

What TPD does a IWC need?

Most likely 800 TPD — that is the median across the 274 IWC models in the Winding Index, and the most common single setting is 800 TPD (59% of models). Settings are per-model, though: check yours in the TPD database before programming a winder.

Which way should a winder turn for a IWC?

IWC's direction profile in the Index is 74% bidirectional, 24% clockwise only and 2% counter-clockwise only. A bidirectional programme is the safe setting for this brand.
