It can repeat the hours and quarter hours. The gold dial has Roman numerals, outer minute dots, blue enamelled numerals, subsidiary seconds dial, and blued snake hands. The case is engine-turned and has a ribbed band with the case maker’s mark TW. The movement is signed and numbered, the case is numbered, and both have matching numbers.
