Hello, and welcome to the first quarter earnings conference call for Amphenol Corporation. Following today's presentation, there will be a formal question-and-answer session. Until then, all lines will remain in a listen-only mode. At the request of the company, today's conference is being recorded.
If anyone has any objections, you may disconnect at this time. I would now like to introduce today's conference host, Mr. Craig Lampo. Sir, you may begin.
Craig Lampo -- Chief Financial Officer
Good afternoon, everyone. This is Craig Lampo, Amphenol's CFO, and I'm here together with Adam Norwitt, our CEO. We would like to welcome you to our first quarter 2022 conference call. Our first quarter results were released this morning.
I will provide some financial commentary, and then Adam will give an overview of the business and current trends. Then we will take questions. As a reminder, during the call, we may refer to certain non-GAAP financial measures and make certain forward-looking statements, so please refer to the relevant disclosures in our press release for further information. In addition, as previously announced, effective January 1, 2022, we aligned our businesses into three new reportable segments.
Effective for the first quarter of 2022, we are reporting results for these new segments, as well as the relevant comparable historical financial data. The company closed the first quarter with sales of $2.952 billion and GAAP and adjusted diluted EPS of $0.68 and $0.67, respectively. First quarter sales were up 24% in U.S. dollars, 25% in local currencies, and 17% organically compared to the first quarter of 2021.
The significant sales increase was driven by double-digit organic growth in the IT data communications, commercial air, industrial, automotive, and broadband markets, as well as contributions from the company's acquisition program. Sequentially, sales were down by just 2% in U.S. dollars and in local currencies and down 4% organically. Adam will comment further on trends by market in a few minutes.
Orders for the quarter were a record $3.441 billion, which is up 26% compared to the first quarter of 2021, and up 5% sequentially, resulting in a strong book-to-bill ratio of 1.17-to-1. GAAP and adjusted operating income was $590 million in the first quarter. And operating margin was a strong 20% in the first quarter of 2022, which increased by 40 basis points compared to the prior-year quarter. Sequentially, adjusted operating margins declined by only 10 basis points, which is significantly better than we typically see in the first quarter.
