Registration No. 333-291557

Waton Financial Limited is filing this Amendment No. 1 (this “Amendment No. 1”) to the Registration Statement on Form F-1 (Registration No. 333-291557), originally filed with the U.S. Securities and Exchange Commission on November 14, 2025 (the “Registration Statement”), as an exhibit-only filing solely to update Exhibit 23.1. Accordingly, this Amendment No. 1 consists only of the facing page, this explanatory note, Part II of the Registration Statement, the signature pages to the Registration Statement, and the exhibit being filed with this Amendment No. 1. The prospectus is unchanged and has been omitted.

Our memorandum and articles of association currently in effect provide that, subject to certain limitations, we indemnify against all expenses, including legal fees, and against all judgments, fines and amounts paid in settlement and reasonably incurred in connection with legal, administrative or investigative proceedings for any person who:

These indemnities only apply if the person acted honestly and in good faith with a view to our best interests and, in the case of criminal proceedings, the person had no reasonable cause to believe that his conduct was unlawful. The decision of the directors as to whether the person acted honestly and in good faith and with a view to the best interests of the company and as to whether the person had no reasonable cause to believe that his conduct was unlawful is, in the absence of fraud, sufficient for the purposes of the memorandum and articles of association, as amended, unless a question of law is involved. The termination of any proceedings by any judgment, order, settlement, conviction or the entering of a nolle prosequi does not, by itself, create a presumption that the person did not act honestly and in good faith and with a view to the best interests of the company or that the person had reasonable cause to believe that his conduct was unlawful.

We have entered into indemnification agreements with each of our directors and executive officers. Under these agreements, we agree to indemnify our directors and executive officers against certain liabilities and expenses incurred by any such person in connection with claims made by reason of their being a director or officer of our Company. We have purchased the directors’ and officers’ liability insurance for the Company’s directors and officers.

During the past three years, our Company has issued securities to certain founding shareholder which were not registered under the Securities Act. We believe that each of the issuances was exempt from registration under the Securities Act in reliance on Section 4(2) of the Securities Act regarding transactions not involving a public offering or in reliance on Regulation S under the Securities Act regarding sales by an issuer in offshore transactions. No underwriters were involved in these issuances of securities. For the history of our share issuances and significant changes in the ownership of our Ordinary Shares, see “Description of Share Capital—History of Share Capital” and “Principal Shareholders.”

Schedules have been omitted because the information required to be set forth therein is not applicable or is shown in the Consolidated Financial Statements or the Notes thereto.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 6, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
