[2] Tokugawa Ieyasu sent his diplomatic advisor and translator Miura Anjin (William Adams) to Iwawada and ordered him to protect de Vivero and his crew.

Honda Tadatomo met with de Vivero, and gave him kimono, tachi swords, cows, chickens, fruit, and sake.

Ieyasu, as temporary ambassador to Spain, held discussions on trade, and offered to provide de Vivero and others with Western-style ships and travel expenses on the condition that they send mining engineers from Mexico.

However, when Teiichi Asahina visited Tōshō-gū in the spring following the broadcast to check the actual clock, he found that the iron parts had considerable red rust and the oil had run out, rendering it inoperable.

[14] During the restoration, clockmakers such as Sugijirō Isada of Tokyo and Namijirō Ishizu of Hamamatsu worked without pay, and the clock began to run again.

The perpetrators were later arrested, but the other 12 treasures were found caught in a fishing net in the ocean at Miho no Matsubara, and although they were all damaged, the clock was the only one that was returned undamaged.

The doors and back are engraved with lines depicting a view of a fortress from a Gothic style arched gate, and the domed upper surface is overlaid with openwork metal fittings in a wave pattern.

[6] An inscription featuring an anthropomorphic expression in a mixture of Spanish and Latin, "HANS・DE・EVALO・ME・FECIT EN MADRID・A・1581", meaning "Hans de Evalo made me in Madrid in 1581," is engraved on an oval plate tacked to the bottom of the dial.

[16] David Thompson, curator of horological collections at the British Museum in the United Kingdom, came to Japan to examine the internal parts of the clock in May 2012.

[2][3] Thompson stated at a press conference that "There are only about 20 similar clocks from this period in existence in the world, and almost all of the internal mainsprings and other parts remain unchanged, including the leather-covered outer case, which is in excellent condition."

[24] This discovery was made in the fall of the same year, when the Shizuoka University Electronics Research Institute, following Thompson's suggestion, took fluoroscopic images of the front side and bottom of the clock.

[5] Katsuhiro Sasaki and Yō Saitō, honorary research fellows of the Science and Engineering Department of the National Museum of Nature and Science, have speculated that a clock in the possession of the viceroy was newly inscribed with the name of de Evalo, who had been promoted to royal clockmaker in 1580, as the work of the royal clockmaker was required as a gift to show the authority of the Kingdom of Spain as well as a sufficient acknowledgement to Tokugawa Ieyasu.

They based this speculation on the fact that there were less than five months between Don Rodrigo's return to Acapulco and his departure for Japan, and there was no time to transport a clock from mainland Spain with such a short period of preparation.
